Title
|
Combined Biometric Reader/RFID Circuit
|
|
Abstract
|
A circuit that combines the functionality of a biometric reader and an RFID circuit is provided. This circuit uses certain functional blocks for processing both the biometric signals and the RFID signals. As a result, the space and power consumed by the circuit are substantially reduced such that the circuit can be formed to fit a free-standing, hand-held reader device. The circuit also may use a single interface from a hand-held device to central processing unit to process digital signals from both the biometric reader and the RFID circuit. In addition, in one embodiment, the circuit may also simultaneously process biometric data signals and RFID signals.
