The design of A33 is a secondary development module for fingerprint identification combined with fingerprint collection and fingerprint comparison. It has a small size, low power consumption, universal interface, high reliability, super simple use, and scalable large capacity 1: N identification ( 3000 fingerprints, non-group identification response time is less than 1.5 seconds) and other advantages, it can be easily embedded in the user system to form a fingerprint identification product that meets customer needs.

A33 adopts imported fingerprint recognition algorithm.

Self-learning function: During the fingerprint recognition process, the newly extracted fingerprint feature value is successfully recognized in the fingerprint database after the recognition is successful, so that the more useful the user is in the use process.

360-degree automatic correction recognition function: Press the correctly registered finger at any angle on the module, the comparison can pass.

The fingerprint recognition rate is low: the maximum can be 0.0001%, that is, one fingerprint is randomly selected among 1 million different fingerprints, and the other fingerprints in 1 million miles are compared with the selected fingerprint in turn, and a recognition pass will occur.

The fingerprint rejection rate is low: the maximum can be 0.0001%. Among the 1 million fingerprints already existing, the fingerprints in the 1 million fingerprints are used to compare 1 million times in any order, and a recognition failure will occur.
