Features 1. Stores multiple fingerprints: The fingerprint scanner can store 10 fingerprints, allowing for multiple account setups. Each family member can have a separate account and automatically log in via fingerprint. 2. 360-degree auto-calibration: 360-degree automatic calibration and recognition. Press your registered finger at any angle on the module to complete the comparison. 3. Multifunctional: Multifunctional design; fingerprint collection, registration, matching, and search can be performed independently. 4. Wide application: This mini fingerprint reader is suitable for fingerprint access control machines, fingerprint searches, attendance machines, fingerprint cabinets, one-touch automated operation, fingerprint writing, fingerprint locks, and fingerprint security. 5. Compact design: This compact and portable computer fingerprint reader boasts low power consumption, a universal interface, high reliability, and ease of use.
