Fingerprint matching includes fingerprint comparison (1:1) and fingerprint search (1:N) methods. Fingerprint algorithms extract features from acquired fingerprint images, representing fingerprint information. During fingerprint registration, each fingerprint is recorded twice, and a composite template is stored in the module. Fingerprint processing involves two processes: fingerprint registration and fingerprint matching. Power supply voltage is DC 3.3V, with an operating current of <60mA and a current of <60mA., Manufacturer: Akfldms
