Chip-and-pin reader device

摘要

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.

主权项

1. A chip-and-PIN reader device, comprising:
a slot for accommodating a chip-and-PIN card; a set of electrodes within the slot and 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, wherein the means for ensuring correct registration comprises a pair of electrodes on each side of the set of electrodes which are to come into contact with the electrodes on the card with each pair of electrodes being spaced from the set of electrodes and from one another within the slot so that when electrodes of a card are aligned with the set of electrodes of the reader device, the card electrodes do not contact either pair of electrodes of the reader, the reader device being adapted to detect a short-circuit of either of the two pairs of electrodes, due to a chip card electrode being misaligned and contacting either of said pair of electrodes, and to signal said short-circuit to the user of the reader device.
