_______________❀Product Information❀______________
1. Multi Function: This optical fingerprint module can complete fingerprint collection, fingerprint registration, fingerprint comparison and fingerprint search function independently.
2. Self Learning: In the process of fingerprint recognition, the latest fingerprint characteristic values will be integrated into the fingerprint database.
3. Autocorrection: This fingerprint reader module supports 360 degrees autocorrection and auto identification, which allow you to press the correctly registered finger at any angle.
4. Low FAR: This fingerprint reader sensor features maximum 0.0001% low false accept rate, that is, when randomly pick one fingerprint in 1 million fingerprints to compare with the others, only one fingerprint in 1 million will be successfully identified and passsed.
5. Low FRR: This optical fingerprint reader adopts 0.0001% low false rejection rate. Among the existing 1 million fingerprints, if 1 million fingerprints are compared 1 million times in any order, only one identification fails.
