How the Module Works
1. Fingerprint features
The fingerprint algorithm extracts features from the acquired fingerprint ie and represents the fingerprint information. The storage, comparison and search of fingerprints are all done by operating fingerprint features.
2. Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process (in which fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N) two ways).
When the fingerprint is registered, two fingerprints are entered for each fingerprint, and the input ie is processed twice. The synthesis module is stored in the module.
When the fingerprint is matched, the fingerprint sensor is used to input the fingerprint ie to be verified and processed, and then it is compared with the fingerprint module in the module (if it is matched with a module specified in the module, it is called fingerprint comparison mode, ie, 1:1 mode. If matching with multiple modules is called fingerprint search, ie 1:N mode, the module gives the matching result (pass or fail).
