Fingerprint logon, 2 times a fingerprint entry 2 entry image processing the synthetic template stored in the module.
Fingerprint matching, fingerprint head sensor input to verify the fingerprint image processing, and then with the fingerprint template module.
The row matched comparison (a template to match the specified module, called fingerprint matching method, ie 1:1 way; if with multiple
Template matching, called fingerprint search, that is, 1: N mode) module gives the matching results (pass or fail).
