A single-chip, fully integrated biometric authentication smart card system-on-a-chip (SoC) has been developed that integrates an analog front-end for fingerprint sensors (FPSs), a high-speed processor dedicated to fingerprint information processing, and a dual-interface smart card system with a secure element. The chip is mounted on a cost-effective single package with a capacitive FPS and a few external capacitors. The implemented biometric smart card system shows a total processing time of 792.5 ms including anti-spoofing fingerprint authentication at a magnetic field strength of 1.05 A/m.
