1. Hold Many Fingerprints: Fingerprint scanner can hold 10 fingerprints, set fingerprints for multiple accounts, set fingerprints for each family member using a separate account, and automatically log in to their own accounts through fingerprints.
2. 360 Degree Auto Calibration: 360 degree auto calibration and recognition function, press the correctly registered finger at any angle on the module to complete the comparison.
3. Multifunctional: Multi functional design, fingerprint collection, fingerprint registration, fingerprint matching and fingerprint search can be done independently.
4. Wide Application: Mini fingerprint reader is used for fingerprint access control machine, fingerprint root search, fingerprint attendance machine, fingerprint storage cabinet, one touch automatic operation, fingerprint printing, fingerprint lock, fingerprint security.
5. Compact Structure: Computer fingerprint reader is compact, easy to carry and store, low power consumption, universal interface, high reliability and easy to operate.
