Operation Principle
Fingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the
matching can be 1:1 or 1:N).
When enrolling, user needs to enter the finger two times. The system will process the two time
finger images, generate a template of the finger based on processing results and store the template.
When matching, user enters the finger through optical sensor and system will generate a template
of the finger and compare it with templates of the finger library. For 1:1 matching, system will
compare the live finger with specific template designated in the Module; for 1:N matching, or
searching, system will search the whole finger library for the matching finger. In both
circumstances, system will return the matching result, success or failure.
