Integrated data entry system including a card proximity sensor for security access control
First Claim
1. An apparatus comprising:
- a keypad unit for displaying a plurality of randomly generated symbols on a keyface, said keyface including a plurality of keys, said keypad unit generating a signal representing one of the plurality of randomly generated symbols when a corresponding key on the keyface is activated;
a proximity sensor for sensing information encoded in a card near the keypad unit, the proximity sensor being hidden within the keypad unit;
a card reader interface circuit coupled to the proximity sensor for reading the encoded information from the card; and
a control circuit coupled to the keypad unit and the card reader interface circuit, the control circuit converting said signal or said encoded information into an identification code.

Abstract
A method and apparatus for access control is disclosed. The apparatus comprises a keypad unit, proximity sensor, a card reader interface circuit, and a control circuit. The keypad unit displays a plurality of randomly generated symbols on a keyface which includes a plurality of keys. The keypad unit generates a signal representing one of the plurality of randomly generated symbols when a corresponding key on the keyface is activated. The proximity sensor senses the information encoded in a card held near the keypad unit. The proximity sensor is hidden within the keypad unit. The card reader interface circuit is coupled to the proximity sensor for reading the encoded information from the card. The control circuit is coupled to the keypad unit and the card reader interface circuit to convert the signal or the encoded information into an identification code.
