| Claims: 1. Tamper-proof restaurant cash register system, wherein a near field communication system identifies the waiter by a token ring that he wears, to register his orders and takings for clearing. 2. Tamper-proof restaurant cash register system as to claim 1 , wherein all meals and drinks ordered are marked with a disposable label on their downside, by which they are recognized when handed over. 3. Tamper-proof restaurant cash register system as to claim 1 and 2, wherein the labels are adhesive to glass and chinaware, but dissolve in dishwashers. 4. Tamper-proof restaurant cash register system as to claim 3, wherein the labels consist of very thin bread, like communion wafers, with an NFC (Near Field Communication, e.g. RFID) antenna printed thereon. 5. Tamper-proof restaurant cash register system as to claim 1 , wherein the counters, whereon drinks and meals are handed out contain a NFC antenna system. 6. Tamper-proof restaurant cash register system as to one or more of the preceding claims, wherein the labels are tagged with codes of the ordered meal or drink in the kitchen or at the bar before being handed over. 7. Tamper-proof restaurant cash register system as to claim 2, wherein the labels are printed upon transferred order from tablet computers as in claim 1. |
FIELD OF THE INVENTION
The invention relates to cash-registers and here particularly to types used in restaurants, where hitherto waiters are operating it for generating vouchers that are handed over to the kitchen and barkeeper to be cleared later with the waiter's cash receipts.
BACKGROUND OF THE INVENTION
There are two main problems that make this system difficult to operate: waiters have to deal with quite irregular work load and so is the kitchen and the barkeeper. So regularly stress is building up that results in mistakes by oversight, and that coincides with opportunities of receiving unregistered drinks and foodstuff or making vouchers disappear before they are picked-up.
TASK OF THE INVENTION
It is therefore the task of the here disclosed invention, to reduce the stress when filing vouchers, as well as to ensure that handed-out meals and drinks are registered to the right waiter.
SOLUTION
The solution is, that handed-out meals or drinks are labelled with an online printed RFID on their downside of glasses and plates and then registered automatically with the waiter receiving it at the counter, both identified by a RFID-System, that is built into the counter and trans- mittet to a computer and cash register system.
DESCRIPTION OF THE INVENTION
The system demands a wireless communication device, by which the waiter registers the orders and transmits it to the kitchen and the bar - this sofar is already installed in many restaurants .
One inventive step is, that each waiter carries an RFID-tagged ring and the tablet identifies her or him by it, so that the tablets can be changed with each shift or occasionally.
That is to avoid discussions later about which order must be booked to whom, if the shift changes in a hurry. The other inventive step is, that the ordered meals are tagged with a disposable RFID-label, that is difficult to change as such, but dissolved and easily removed in the dishwasher-machine.
In a preferred embodiment the labels consist of very thin pieces of bread, like communion wafers, with an NFC (Near Field Communication, e.g. RFID) antenna printed thereon, with an ink that contains fine metal particles. These stick -only slightly moistened- on glass and chinaware. However, it is also possible to apply adhesive glues.
When taking over, a reader system under (or above) the desk compares the passed meals or drinks with the orders registered and books off all items handed out to the waiter, who had ordered it and who is identified at the counter again by his ring with RFID token. If there is no match, an alarm signal will be executed.
Description of the invention along to the drawing:
Fig. 1 describes the system, in which the waiter 1 , wearing a RFID token ring 2 is identified at a tablet communication device 3, whereon he registers ordered meals and drinks.
These orders 4 are transmitted by Bluetooth ® or other wireless communication 5a and 5b to a clearing computer 6 and a RFID label printer 7 in the kitchen and another one 8 at the bar. The labels printed therewith are attached under bottles and glasses 9 or menue plates 10 to be handed out.
The counter 11 , where they are handed over, contains an RFID -reader 12 to and the system compares the labels on Meals and drinks with the orders and the waiter (again identified by his RFID-token-ring) who takes it, and issues an alarm if they do not match. The drink or meal is then booked to the waiter's account on the cash-register 13 for clearing.
