Background When a person is mobile, e. g. travelling on an airplane, and finds an article of interest in a magazine, that he wants to keep, he has but a few options. Either he tears out the article from the magazine or takes the whole magazine with him, or he writes down the name of the magazine so that he can order a copy when he is back at home. Neither of the options is satisfactory. If he tears out the article or takes the magazine with him, the next passenger will be unable to read the article. If he writes down the name of the magazine or tries to remember it, he will probably forget all about it and never order any copy. This problem is not only a problem of the person who reads the article and wants to keep it, but also a problem of the author of the article and the publisher of the magazine, who want to distribute the information in the article.

A similar problem may arise when a person sees an advertisement for a product. If he becomes interested and wants to obtain more information about the product, he then needs to remember the name of the manufacturer or its www-address until he has the opportunity to seek this further information. At the time when he actually has the possibility to obtain more information, he has, however, often lost interest or forgot about it. This is very unsatisfactory for the advertiser, who catches the attention of a potential buyer but fails to establish a relation with him.

These are but examples. There are many more similar situations where an information seeker fails to obtain information and an information provider fails to establish contact with an interested party.

Summary of the invention Thus, a first object of the present invention is to enable an information seeker to request information in a simple way.

A second object is to enable an information provider to distribute information in a simple way.

One or both of these objects are achieved by means of a message information system according to claim 1, a device according to claim 16, a method according to claim 33, a product according to claim 36, a computer-readable medium according to claim 41, and systems for distributing information according to claims 43 and 47.

More particularly, according to a first aspect, the invention provides a message information system, which comprises a plurality of objects, each one of which is associated with an identifier which identifies the object; first database means, which store object information relating to said objects such that the object information relating to each object is retrievable by means of its identifier; a plurality of user devices, each one of which comprises receiver means, which are adapted to receive the identifier of an object selected by the user of the user device, and sending means which are adapted to send a request message to a predetermined address and to include in said request message the identifier received from the object selected by the user as well as an indication of an information receiving address selected by the user of the user device; a request message receiver, which is adapted to receive the request messages from the user devices; and processing means, which, in response to the receipt by the request message receiver of one of the request messages, are adapted to retrieve from the first database means the

object information relating to the object identified by the identifier included in said one of the request messages, to generate an information message which includes the object information retrieved from the first database means, and to send the information message to the information receiving address selected by the user.

This message information system solves the problems accounted for above. When the traveller finds his article of interest or when he sees an advertisement for an attractive product he needs only to take out his user device and register the identifier of the article or advertisement. The user device sends the identifier to a predetermined address. As a result a copy of the article or information about the product in the advertisement is sent to an address selected by the traveller, e. g. to his electronic mailbox at home.

This message information system is advantageous both for those who seek information and for those who distribute information. The one who seeks information may collect information and have it sent to a selected address, which may be his own or that of another person or company. As will be evident from below he may moreover control the format and the extent of the information sent to him. The one who distributes information obtains on his part a possibility to evaluate the response to the distributed information. He may find that a specific advertisement among a plurality of advertisements for the same product catches much more attention than the others.

He may then decide to concentrate on this advertisement in the future. He also gets an opportunity to start a dialogue with those who request further information on the product of the advertisements.

The message information system is also advantageous in that it allows an information seeker to obtain and an information provider to provide customised and specific information in an automatic manner.

The message information system is principally intended for providing information in relation to tangible objects.

The message information system is especially advantageous when the objects are physical documents, because it solves the problem of how to obtain a copy of a document when no copying machine is available. It also solves the problem of how to obtain an electronic version of a document when no scanner or other device which converts text and images on a physical document to electronic text and images is available. The user may moreover obtain a dynamic copy of the document, i. e. a copy of the document with further information added.

The objects may be of different types because the message information system is a general system which any information provider may use for distributing information. The system can comprise any number of objects. All objects of the same kind e. g. all documents with identical content, could of course be marked with one identifier.

The user devices are preferably portable so that the identifier of any object independently of its location can be registered by the user devices.

In a preferred embodiment the user devices comprise mobile phones. Today, many people always carry their mobile phone. If the user device is implemented in a mobile phone or as an add-on to a mobile phone, no additional devices need to be carried by the user in order to use this message information system.

The mobile phone may have switching means, e. g. a press button, for switching the phone between an information requesting mode, in which it operates to receive identifiers and send request messages, and a phone mode, in which it operates like an ordinary mobile phone.

The sending means are suitably adapted to generate the request message in electronic form, preferably in

digital form, so that it can be computer-processed when received by the request message receiver.

The sending means may send the request message to the predetermined address by means of cables, by wireless technique or by any other appropriate technique. The wireless technique is preferred because it makes the user device fit for use anywhere.

The sending means preferably comprise a data processor, which controls the generation of the request message, and a transmitter, which under the control of the processor transmits the request message.

The predetermined address to which the request message is sent is preferably an electronic address so that the request message can be computer-processed.

Normally it is the address of a remote location.

The identifier is usually composed of a plurality of digits and/or letters. It can be used in coded form. It may be transferred to the user device directly from the object identified by the identifier or from a point close to the object. It may be received by the user device when the user device is at a limited distance from the object or when the user device is very close to or in contact with the object. It may be in almost any form and it may be received in almost any manner. Preferably the receiver means receives the identifiers"automatically", i. e. without the user having to manually input the individual digits, letters or the like. Instead the receiver means register electromagnetic waves which represent the identifiers.

In one embodiment, a transmitter, preferably a radio transmitter, e. g. a transponder or a RFID device (radio frequency identification device), is associated with the object and adapted to transmit the identifier in the form of electromagnetic waves. In this embodiment the receiver means of the user device are adapted to register the identifier in the form of electromagnetic waves when the user device is activated by the user. This embodiment has

the advantage that the object does not need to be within reach of the user. Thus, the user may e. g. request and obtain information about objects in a show-case in a museum or behind the glass window of a shop.

As an alternative the identifier may be in such a form that the user needs to bring the user device close to the object in order to register the identifier. The identifier may e. g. be optically read by a reader in the receiver means of the user device. It could be an alphanumerical code, which is applied on the object and which could be read by an optical scanner and decoded by an OCR program.

In a preferred embodiment the identifiers are, however, in the form of bar-codes, which are applied on the objects or in their vicinity, and the receiver means of the user devices comprise a bar-code reader. The bar- code is advantageous in that it is space-saving and that the bar-code reader and the means for decoding the bar- codes are easy to realise and to miniaturise. The expression"bar-code"shall be broadly interpreted. It includes all kind of machine-readable codes that are based on lines, dots and other geometrical patterns.

When having been received by the user device, the identifier is stored in the user device at least temporarily until it has been included in the request message.

The identifier may preferably be supplemented by a distinctive feature, such as a specific colour, an added symbol, a frame, a specific signal or the like, for indicating to the user that the object which is associated with the identifier is part of this particular message information system. In a preferred system, the identifier is also supplemented with or includes a system identification, which is recognised by the user devices and/or the processing means of the system. In this latter case the user devices comprise means for detecting this system identification, e. g. appropriate software code, so

that sending of the request message is only enabled when the system identification has been detected by the detecting means. Alternatively, the sending means may be adapted to include the system identification in the request message, so that the request message receiver may decide whether the received request message comprises an identifier of the message information system or not.

The information receiving address is preferably an electronic address to which an electronic message is sent so that the message information system can be fully automated.

The information receiving address can be selected by the user when he registers as a user of the system and when he changes his user registration and/or when he uses his user device for requesting information.

Preferably the user device is arranged in such a way that the user may select between different information receiving addresses so that he may request that information of personal interest is sent to his home com- puter, whereas information relating to his work is sent to his office computer. For this purpose the user device may comprise selecting means, such as keys or software menus, that enable the user to select between at least two information receiving addresses. The information receiving addresses may be stored in the user device or elsewhere, e. g. in a database connected to the request message receiver. The user may of course also request that the information is sent to another person than himself.

The information receiving address selected by the user can also be the address of the user device from which the request message is sent. This could be the case when the information is needed immediately. However, in the preferred embodiment the information receiving address is associated with an information receiver other than the user device from which the request message is

sent, because the user device will often be a device with limited information receiving capability, if any.

The indication of the information receiving address must enable the system to determine where the information relating to the object identified by the identifier in the request message should be sent. The indication may be the information receiving address itself. It may also be a pointer to a memory location where the system may find the information receiving address. In a preferred embodiment the indication of the information receiving address comprises a unique user identity, e. g. the user's SIM card number when the user device is a mobile phone or a unique manufacturing number of the user device or the civic registration number of the user supplemented by a PIN code. In the preferred embodiment, the system further comprises second database means, which are adapted to store the unique user identities and for each unique user identity one or more information receiving addresses selected by the user.

The indication of the information receiving address may be permanently stored in the user device or input when the user device is used. The latter alternative allows several users to use the same device.

In order to increase the flexibility of the system, it may preferably also comprise user registration means, which are adapted, when activated by a user of the system, to register user information relating to said user. The processing means may be adapted to use said user information for the generation of the information message. The user may e. g. register in which language the information should be sent to him, the extent of the information to be sent, whether the information provider is allowed to contact him and to continue to send information. This enables the information provider to customise the information and the information seeker to receive tailored information, thus enabling user integrity control.

The message information system according to the invention may be expanded successively by the addition of new user devices and new objects. For this purpose, the message information system comprises a supply of unused identifiers, which are to be associated with objects and corresponding object information. These unused identifiers may be acquired by information providers who want to mark their objects with identifiers so that users of the system can obtain information relating to these objects. The objects may be marked with labels on which the identifiers are applied.

The information message which is sent to the information receiving address can include information in the form of text, images, video, speech or any other possible form of information which could be sent by an information message, preferably an e-mail. The information which is sent is determined by the information provider. It may be dynamic and different from user to user and from time to time.

In the message information system according to the invention all information relating to all the objects may be stored in the first database means and processed by the processing means. In this case, the request message receiver, the database means and the processing means may be operated by one system administrator. Preferably, there are, however many first database means, each of which stores information relating to one or more of the objects and each of which has its own processing means.

In this case the request message receiver directs the request messages, sometimes in a refined form, to the appropriate first database means. Different combinations of these two alternatives are also conceivable. There may e. g. be central processing means at the request message receiver which retrieve the requested information from the relevant first database means among a plurality of first database means. This may have the advantage that

the information provider does not know to whom the information is sent.

It should also be realised that the request for information is sent without any contact having to be established with the information provider or the request message receiver. It is a"simplex"request.

In a second aspect, the invention relates to a device for requesting information regarding an object, said device comprising receiver means, which are adapted to receive an identifier identifying the object and sending means, which are adapted to send a request message to a predetermined address and to include in said message the identifier as well as an indication of a selected information receiving address to which an information message containing object information regarding the object is to be sent in response to the receipt of the request message at the predetermined address.

This device is applicable in a message information system according to the invention. The device may have any of the further features mentioned above in relation to the user devices. It has the advantages which appear from above.

The predetermined address may be an address to a central database storing information on all objects which are associated with identifiers of this kind. However, in the preferred embodiment it is not the direct address to the database where information relating to the object corresponding to the identifier in the request message is stored, but it is the address to a controller, e. g. the request message receiver of the message information system according to the invention, which directs the request message to the database of the information provider who stores the information corresponding to the identifier in the request message.

The predetermined address is preferably an electronic address, i. e. an address on which electronic

messages can be received. It could be an IP-address (an Internet Protocol address). It is suitably stored in the user device or programmed the first time the device is to be used. Alternatively it may be a supplement to the object identifier and found by the sending means. The predetermined address need not be explicitly known to the device. The device may e. g. send the request message to a mobile network operator, who directs it to the predetermined address.

In one embodiment of the device, the receiver means are detachable from the sending means so that the receiver means can be used on its own for registering one or more identifiers. When the receiver means are attached to the sending means, the identifiers can be sent to the predetermined address.

In another embodiment the receiver means are separate from the sending means and communicate via a short range radio link with the sending means. This embodiment has the advantage the receiver means may be very small so that they can be carried everywhere without problem. They may e. g. be implemented in a pen-shaped envelope. In this case the sending means need not be small, but can be implemented in e. g. an ordinary telephone, to which the identifiers are transferred via the short range radio link.

The device may have decoding means for decoding or converting the identifier signals received by the receiver from the object, which may be radio signals, optical signals or any other signals to a form which may be handled by the sending means. The decoding means may also be used for finding the identifier if the signals received by the receiving means comprise other information than the identifier. When the identifier is an alphanumerical identifier the decoding means may e. g. comprise an OCR program.

In a third aspect, the invention relates to a method for requesting information relating to a tangible object,

which is provided with an individual identifier, comprising the steps of transferring the identifier from said object to a message generating means; generating, in said message generating means, an electronic request message, and including in said electronic request message the identifier and an indication of a selected informa- tion receiving address; and sending the request message to a predetermined address with the purpose of obtaining, at the selected information receiving address, an infor- mation message containing the information relating to the object.

This method can be used in a message information system according to the invention or in other systems where information relating to a selected object can be obtained by sending an identifier of the object to a predetermined address. The above-described steps which are carried out by the message information system can be part of the method separately or in combination.

In a further aspect, the invention provides a product which is marked by a code of a predetermined format, which includes an identifier, which identifies the product and which is machine-readable such that information relating to the product can be obtained at a selected information receiving address by sending a request message which includes the identifier and an indication of the selected information receiving address to a predetermined address.

The advantage of marking a product by a code of this kind is that it enables a user to order e. g. a copy of a document or further information regarding the product, from a predetermined address in an automated way without having to write down the title of the document or without having to specify the product.

The code may be any kind of code that is suitable for marking an object. Preferably, it should be compact so that the marking could be made in a rather small area.

The code may include the predetermined address. This is advantageous when several parallel information systems are operating. The same device could then be used for ordering information in different information system. As an alternative, the code may be associated with a distinctive feature which is characteristic of the information system in which the code is applicable so that e. g. the device used for reading the code can determine where to send the request message.

The product may be marked by further codes, which enable the reader to order different information about the object. If e. g. the object is a document, a first code may be used for requesting a copy of the document and a second one for requesting a more detailed background to the content of the document.

The product may be used in a message information system according to the invention. It may have any of the feature described above in relation to the objects of the message information system.

In yet another aspect, the invention provides a computer-readable medium, on which is stored a computer program of instructions for a general purpose computer, comprising, in combination, means for receiving an identifier identifying an object, in relation to which information is obtainable on request, means for generating an electronic request message for requesting the information and for including in said request message the identifier as well as an indication of a selected information receiving address, which is supplied as an input to the computer program, and means for sending said request message to a predetermined address.

It is advantageous to generate the request message by means of a computer program, which could be installed in a special-purpose user device, which is used specifically for registering identifiers and sending request messages, or in a general purpose device, like an ordinary telephone or a computer. In the latter case, a

scanner or a bar-code reader or the like may be used for registering the identifier, which then is transferred to the telephone or computer, where the computer program receives the identifier and generates and sends the request message.

The computer program may be used in a message information system according to the invention and carry out any of the steps in the user device.

In yet another aspect, the invention provides a system for distributing information, comprising a database means for storing object information relating to a plurality of objects, each of which is associated with an identifier, and processing means, which, in response to the receipt of an electronic request message including the identifier of one of said plurality of objects as well as an indication of an selected information receiving address, are adapted to retrieve the object information relating to said one of the plurality of objects by means of the identifier included in said electronic request message and to generate an information message containing the retrieved object information and to send the information message to the selected infor- mation receiving address.

This system for distributing information is advantageous for information providers. The distribution can be handled automatically by the processing means in the form of computers, which retrieves the information specified in the request message and sends it to the selected information receiving address.

This system may comprise any of the features mentioned above in connection with the message information system of the invention, either separately or in combination. It may be used in the message information system according to the invention. It may be used as a centralised system, which stores information about all the objects, or as a system of a specific one of a plurality of information providers, which handles

information relating to the objects of that information provider.

In a further aspect the invention provides a system for distributing information, comprising database means, which are adapted to store a plurality of different identifiers identifying objects in relation to which object information is obtainable, and, for each identifier, a corresponding information storing address, which is useful for finding the object information, and furthermore to store a plurality of unique user identities, and for each unique user identity, at least one selected information receiving address, and further comprising processing means, which, in response to the receipt of an electronic request message including one identifier of said plurality of identifiers as well as one unique user identity of said plurality of unique user identities, are adapted to retrieve the information storage address corresponding to said one identifier and the selected information receiving address corresponding to said one unique user identity and to generate a secondary request message including the identifier and the selected information receiving address and to initiate the sending of an information message containing the requested information relating to the object to the selected information receiving address by sending the secondary request message to the information storage address.

This system for distributing information is advantageous in that the information relating to the objects need not be stored in a central database which is handled by the system administrator, but the information can be stored in different databases of the different information providers. The system only stores information about the users and addresses to the different information providers. Thus, the system does not need to know for what objects the information providers use their acquired identifiers. The system may nevertheless store

object information of information providers who lack the means to take care of the request messages. It may also generate and send the information messages, even though the information is stored in the database of an information provider.

Preferably, the processing means comprises a computer.

This system may also comprise any of the applicable features mentioned above in connection with the information system of the invention, either separately or in combination. It may be used in the information system above or in any similar system.

Brief description of the drawings Further aspects and details of the invention will appear from the following description of preferred embodiments, reference being made to the accompanying drawings.

Fig. 1 is a schematic view of an embodiment of an information system according to the invention; Fig. 2 is an embodiment of a product according to the invention; Fig. 3 is a schematic view of an embodiment of a device for requesting information according to the invention.

Fig. 4 is a schematic view of an alternative embo- diment of a device for requesting information.

Detailed description of preferred embodiments Fig. 1 shows a message information system which comprises a plurality of objects 1, a plurality of user devices 2 to be used by users U of the system (for reasons of simplicity, only one user and one user device is shown in Fig. 1), a request message receiver 3, which is associated with a database 6 and processing means 7, a plurality of database means 4, each one of which stores information relating to the objects 1 and is associated with processing means 8, and two information receivers 5

with different information receiving addresses (IRA (1) and IRA (2)).

The objects shown in Fig. 1 are an article containing text and an image which is associated with an identifier ID1, a document containing only text, which is associated with an identifier ID2, a book, which is associated with an identifier ID3, a painting associated with an identifier ID4 and a historical building associated with an identifier ID5. These objects are only examples of objects which could be marked by identifiers.

It should be understood that a real message information system would comprise many more objects.

The user device 2 is shown as a mobile telephone. It is provided with receiver means for receiving the identifiers from the objects 1 and sending means for sending request messages requesting information about the objects 1. The user device 2 is described more in detail in Fig. 3.

The system further comprises user registration means 9, which may be implemented as an Internet site and which in Fig. 1 are shown as associated with the database 6 to illustrate that the information registered by the user is sent to the database 6.

The user U is a registered user of the system. At the Internet site, he has registered the SIM-card number of his mobile phone as his unique user identity UUI, his name, and two information receiving addresses, viz.

IRA (1), which is his e-mail address at his office, and IRA (2), which is his private e-mail address. He has also registered a user profile UP, which includes his preferred language which is English. All this information regarding user U is stored in the database 6 connected to the request message receiver 3 so that the information can be retrieved by means of the unique user identity UUI. It should be understood that the database 6 also stores the corresponding information of all the other users of the system.

Assume now that the user U is on holiday and visits a historical site. He gets interested in a temple. On the temple is mounted a small plate with a bar-code.

The bar-code includes the identifier IDS. It has been bought from the message information system administrator by the authority responsible for the historical site. When buying the right to use identifier IDS, the authority informed the message information system administrator of the address B of its database 4, which would store the information about the temple. This address B is stored in the database 6 of the request message receiver 3 so that it can be retrieved by means of the identifier IDS. It should be understood that the database 6 also stores the corresponding address information of the objects identified by the identifiers ID1-4 and of all other objects included in the system.

The user U now brings out his user device 2, turns it on and moves it over the bar-code on the temple. As a result the identifier ID5 is received by the receiver means. The sending means of the user device then generates a request message including the identifier ID5 of the selected object and the unique user identity UUI.

Since the user has had the opportunity to register more than one information receiving address, he is prompted by the user device 2 to select which of these addresses the information should be sent to. He selects his home address which is the first address and which is indicated by the digit"1"added to the UUI.

This request message or request code UUI1+IDS is sent by the mobile phone 2 to its mobile network operator 10, which forwards it to the request message receiver 3.

The processing means 7, which are implemented as a computer connected to the receiver, uses the unique user identity UUI2 for retrieving the information receiving address IRA (1) to which the information regarding the temple is to be sent and for retrieving the user profile UP. Furthermore it uses the identifier ID5 to retrieve

the address B of the database 4 which stores the information regarding the temple. The processing means 7 then sends a secondary request message to address B including the information receiving address IRA (1), the identifier ID5 and the user profile UP.

The processing means 8, which are implemented as a computer connected to the database 4, receive this secondary request message IRA (1) +ID5+UP and use the identifier ID5 for finding the requested information INFO regarding the temple and the user profile UP for customising the information. This time the information consists of a several pages of text in English with accompanying images. Next time a user requests information about the temple using the same identifier, the information provider may however have added new text to the information. The processing means 8 generate an electronic information message and include the information INFO about the temple in this message.

Finally the information message is sent via Internet to the selected address IRA1. When the user returns from his holiday, he finds the requested information in his electronic mail box.

Fig. 2 shows another example of an object which could be used in the information message system of Fig 1.

The object is a magazine, which on page 32 comprises an article concerning patents. In the lowest right-hand corner, the article is provided with a bar-code 20. The bar-code is supplemented with a distinctive feature in the form of a flag 21. The flag 21 indicates that this is a bar-code by means of which a copy of the article can be ordered. The bar-code 20 and the flag 21 is printed at the same time as the article. The format of the bar-code 20 is governed by a standard. The first bars of the bar- code is a system identification which is common for all the barcodes of the system. The remaining bars represent an identifier which identifies the article.

Fig. 3 shows the user device 2 of Fig. 1 more in detail. The user device is an ordinary mobile phone with an antenna 31, a keypad 32, a microphone 33, a loudspeaker 34, a display 35, a transmitter part for transmitting calls (not shown) and a receiver part for receiving calls (not shown).

The phone has however been provided with additional features in order to enable a user to request informa- tion. First the phone has been provided by receiver means in the form of a bar-code reader 36. More particularly, an optical reader head 37 of the bar-code reader 36 is placed in the antenna of the mobile phone. The optical reader head is connected to a controller 38 and a memory 39, which also are parts of the bar-code reader. The controller 38 converts the bar-codes read by the optical reader head 36 to digital form and stores them in the memory 39. The memory 39 moreover stores a predetermined address to which the request message is to be sent. The controller 38 and the memory 39 may be implemented in the ordinary parts of the mobile phone or may be supplemental parts.

Second, the phone has been provided with sending means, which are adapted to generate and send a request message. The sending means comprise a data processor 40 with a suitable software program and a transmitter 41.

The transmitter is preferably the same transmitter as is used by the phone when it is used for normal phone calls.

The data processor can also be a processor which already exists in the phone. The software must of course be added.

Finally, the mobile phone 30 has a key 42 for switching the phone between a bar-code-reading mode and an ordinary telephone mode. When the key 42 is pressed by the user, a signal is sent to the data processor 40, which triggers the phone to switch the mode.

When the mode has been switched, the user moves the optical reader head over a bar-code, e. g. the bar-code 20

of Fig. 2. As a result, the bar-code is stored in the memory 39. When at least one bar-code has been read, the program of the processor 40 prompts the user to select, on a menu displayed on the display 35, the information receiving address to which the information is to be sent.

When the selection of an address has been made the processor 40 prompts the user to press the key 42 anew, to indicate that a request message is to be sent. The processor 40 then retrieves the bar-code stored in the memory and the number of the SIM-card of the mobile phone. The bar-code, the indication of the information receiving address selected by the user and the SIM-card number form the request message. Finally, the processor 40 controls the phone to send the request message to the predetermined address stored in the memory 39. The SMS channel of the phone may be used to send the request message.

In this example, the predetermined address is the number of the request message receiver 3 of Fig. 1, which upon receipt of the message processes it as described in connection with Fig. 1.

In an alternative embodiment, the receiving means and the sending means are implemented as an add-on to the mobil phone. The add-on could be connected to the system bus of the mobile phone.

Fig. 4 shows an alternative embodiment of the user device. In this embodiment, the device consists of two separate parts, a bar-code reader 50 in the form of a pen and sending means 51 implemented in an ordinary fix telephone.

The bar-code reader 50 has an optical reading head 52, which is placed in the tip of the pen, a controller 53, which converts the bar-codes to digital form, and a memory 54, which stores the bar-codes. It further has an on/off button 55 for turning it on/off, a short range radio transmitter 56 for transmitting the recorded bar- codes, which are stored in the memory 54 to the telephone

51, and a send button 57 for controlling the transmission to the telephone 51.

The telephone 51 has, apart from its ordinary components, an information requesting part 58, which includes a short range radio receiver 59 for receiving the bar-codes from the bar-code reader pen, a memory 60, which stores the received bar-codes and a unique user identity, which may be input to the information requesting part or received from the bar-code reading pen, a data processor 61 with appropriate software, which generates a request message, which includes one or more bar-codes read by the bar-code reading pen, the unique user identity, and if required an indication of to which of the information receiving addresses selected by the user the information is to be sent. The selection could be made by means of keys on the bar-code reading pen, which in this case may comprise a small display. When the information requesting part 58 receives one or more bar- codes from the bar-code reader pen 51, the processor 61 generates the request message in such a form that it could be sent by the ordinary components in the telephone and it triggers the telephone to send the request message to a predetermined address, which could be the address of a second computer.

When the user finds the article of Fig. 2 of which he wants to have a copy, he turns on the bar-code reader 50 and moves it over the bar-code 20. The bar-code is stored by the controller 53 in the memory 54. The user then turns off the bar-code reader. When the user returns home he turns on the bar-code reader 50 and puts it close to the telephone 51. He presses the send button 57, whereupon the bar-codes stored in the memory 54 is transferred to the information requesting part 58 of the telephone. The processor 61 prompts the user to indicate to which address the information is going to be sent, if this address has not already been indicated by means of the pen. It includes this indication in the request

message together with the bar-code. The request message is then sent by the telephone to a predetermined address, which is pre-programmed in the information requesting part.

In yet another embodiment the sending device above could be an ordinary general purpose computer, provided with a short range radio receiver and appropriate software for generating the request message, including the bar-code identifying the product in relation to which the user wants information and the indication of the selected information receiving address, and for sending the message via Internet to a predetermined address.

The short range radio link may be replaced by a IR- link or any other appropriate link.
