Welcome to the store! 1. Multi-fingerprint support: The fingerprint scanner can store 10 fingerprints, allowing setup for multiple accounts. Assign fingerprints for each family member with separate accounts and automatically log in through fingerprint recognition. 2. 360-degree automatic calibration: 360-degree automatic calibration and recognition function. Press the correctly registered finger at any angle on the module to complete the comparison. 3. Multi-functional: Supports fingerprint collection, registration, matching, and search independently. 4. Broad application: Mini fingerprint scanners are used for fingerprint control machines, fingerprint root searches, fingerprint tracking machines, fingerprint storage cabinets, fingerprint automatic doors, fingerprint printing, fingerprint locks, and security systems. 5. Compact design: The fingerprint scanner is compact, easy to carry and store, low power consumption, universal interface, high reliability, and user-friendly.
