This invention relates to a method and system to ensure the safe use of magnetic strip cards in order to prevent the theft of information contained in the magnetic strip of a industry standard magnetic strip card.

The applicability of this invention addresses the physical safety of magnetic strip cards and the security of embedded private information.

It's common knowledge that frauds on magnetic strip cards delivered by financial institutions are increasingly widespread IT crimes causing severe material damage and urging further precautions by issuers of cards, which ultimately is leading to a more complex use of such cards. Frauds to ATMs or to any devices using magnetic strip cards for cash payment or cash withdrawal is globally known as "card skimming". This type of crime has thoroughly and rapidly spread in the recent years with major consequences on losses, across the world and the main reason for such increased trans-border crime rate is the poor effectiveness of current security systems.

To avoid this, the world association of magnetic strip card issuers, EMV (EUROPAY, MASTER and VISA) implemented the integrated chip solution for bank cards which actually slowed down the spreading of crimes in Western Europe and shifted the focus of perpetrators to East and mainly to the United States of America.

Currently, there are several anti-skimming solutions and systems in use, such as the slow and gradual removal of the card or protection devices for card insertion slot, bur their capacity to stop the phenomenon is rather symbolic as their existence did nothing but to encourage offenders to find more efficient and improved solutions.

To limit fraud, issuers and producers of magnetic strip cards defined internal rules to limit payments or to modify cards, which clearly brought further costs. One of the in-house protection solutions stipulates that users from abroad must confirm any cash withdrawal by phone. Such instances have also a negative impact on the image besides the financial disadvantage and are weakening or otherwise shake faith in financial institutions issuing magnetic strip cards, as well as discourage the use of card transactions.

The proposed method to increase security of magnetic strip cards usage eliminates all disadvantages mentioned above, by receiving the card perpendicularly compared to regular use, and shifting it with 90° afterwards to reintegrate the card to the regular flow. This method makes any skimmer-type data reading device futile in the sense that in order to read data, the skimmer actually needs to pass the magnetic strip gradually over a reading head. The perpendicular insertion of the card, compared to regular use, makes the reading of magnetic strip-embedded data impossible.

The system that implements the method presented above, consists of a half-cylinder with a special slot of a thickness almost similar to the magnetic strip card and wide of one card length, a mechanical card loading and rotating device, card presence and position sensors, motors to drive the mechanical system, an electronic command and control module of the system and a solid security box in which all system components are installed.

The system proposed, according to the invention, accepts the magnetic strip card in a manner that renders useless any skimming device, as the card is no longer inserted on the strip reading direction. Once received and secured in the rotating half-cylinder, the card is rotated with 90° and introduced in the regular operational flow of the magnetic card device.

All magnetic strip card readers, both authorized and illegal, read data by passing the strip over a reading head which gradually retrieves the embedded information. Illegal readers are at all times concealed in front of the card's insertion slot to record information from all cards used.

The invention has the following advantages:

• Makes impossible the reading of data embedded on magnetic cards by illegal devices

• Eliminates frauds perpetrated by the unauthorized reading of strip embedded data

• Increases the efficiency of the electronic payment system through the opportunity to remove internal safety measures imposed by magnetic strip card issuers and producers

Further is presented an example of implementing of the invention in connection with the figures from 1 to 3 that describe:

• Fig 1 - perspective of the magnetic card security system, according to the invention

• Fig 2 - block diagram of the proposed magnetic card security system.

• Fig 3 - example installation on an existing ATM

The system for the safe use of the magnetic strip cards includes in the proposed model a half-cylinder 1 equipped with a special slot of a thickness almost similar to the magnetic strip card and wide of one card length, a mechanical card loading and rotating device 2, card presence and position sensors 3, electrical motors for the mechanical system 4, the overall electronic command and control module 5 and the physical security box 6 containing all system parts.

When inserting the card into the special slot of half-cylinder 1 , sensors 2 sense the card and send a digital signal to the electronic command and control unit 5 to signal that the card is in the pre-set position which further transmits commands to the electric motors 4 which drive the loading and rotating device 2 in order to rotate and load the card into de device performing the transaction and the safe reading of the magnetic strip card. Upon completion of card transactions, the device ejects the cards to the safety system which takes it over through the loading and rotating device 2 and delivers it back to the user in the same manner as it was inserted, thus removing the risk of illegal reading.
