3.3V Optical Fingerprint Recognition

A compact, low-power optical fingerprint recognition module built around the AS608 sensor, designed specifically for secure, embedded access applications such as electronic door locks and entry controllers. Operates natively at DC 3.3V with low operational current. Typical dimensions: ~32 mm × 28 mm × 20 mm; lightweight construction supports discreet mounting. Image acquisition uses optical refraction principles to produce high-fidelity ridge-valley contrast. Internal processing extracts unique fingerprint features (minutiae), constructs templates during dual-scan registration, and executes fast 1:1 or 1:N matching using stored templates. All biometric logic resides on the module — no host CPU image analysis needed. Templates are stored in protected on-chip memory; raw images are discarded immediately after feature extraction.
