<p>The invention provides a reader device 12 for a chip-and-PIN, or smart, card 15. It includes a slot for the card and a plurality of keys 16 including numeric keys 0-9 and possibly enter/re-start keys. A set of electrodes (32) is provided for making contact with corresponding electrodes on the chip card. A comparing means compares the PIN entered by the user with the PIN stored on the chip and provides a signal indicative of a wrongly entered PIN. If the correct PIN is entered, then an encryption means encrypts the card-number data, and the encrypted card-number data is transmitted to a mobile communications device 10. The reader device may also be equipped to read a magnetic-stripe type card. The reader device may also have an alignment means which could include electrodes (34) that are short-circuited when the card is incorrectly aligned. The card may also provide for biometric identification, perhaps by registering a photograph of the user on a remote server at first use of the card.</p> |
