Abstract

Invention provides a fingerprint biometric capture sensor device and method for capturing and either reconstructing fingerprint image or information concerning fingerprint without actually performing fingerprint image reconstruction. In another aspect, fingerprint biometric capture sensor device is integrated with on-chip data buffering. In another aspect, sensor device is integrated with on-chip processor. In another aspect, invention provides a fingertip sensor system including: fingertip sensor device generating analog first electrical signal representing feature of fingertip in response to placing fingertip in proximity with sensor device; analog-to-digital converter coupled with and receiving analog first electrical signal from sensor device and converting first electrical signal to a digital second electrical signal; at least one buffer coupled with and receiving digital second electrical signal from analog-to-digital converter and storing information corresponding to at least a portion of digital second electrical signal therein; and logic controlling operation of sensor, analog-to-digital converter, buffer, and host interface circuit.
