Abstract: The invention provides a chip-and-PIN reader device having a slot for accommodating a chip-and-PIN card, a set of electrodes adapted to come into contact with corresponding electrodes on the card when the card is inserted into the slot, and a means for ensuring correct registration between the electrodes on the card and the set of electrodes of the reader device. The means for ensuring correct registration may include two orthogonally disposed walls of the slot, against which the card is pushed. Alternatively, the means may include a pair of electrodes on each side of the set of electrodes of the reader, which are short-circuited when the chip electrodes are not correctly registered with the reader electrodes. The short-circuit is flagged to the user of the card. The reader may also be equipped to read an MSR-type device.

Abstract: The invention provides a chip-and-PIN reader device, which includes a slot for a chip card and a plurality of keys including numeric keys 0-9 and possibly an enter key and a restart key. The enter key is used to indicate to the device that the PIN has been fully entered and the restart key is used to indicate to the device that a mistake has been made in entering the PIN and that the PIN is to be re-entered. A set of electrodes is provided for making contact with corresponding electrodes on the chip card. A reading means connected to the set of electrodes reads the entered PIN and the card-number data stored on the chip. A comparing means compares the PIN entered by the user with the PIN stored on the chip and provides a signal indicative of a wrong entered PIN. A restart means is provided, which allows the PIN to be re-entered.
