Why You'll Love It
- 3 Ways to Unlock: Use your fingerprint, the companion mobile app, or the USB electronic key — whichever is most convenient for the moment.
- Lightning-Fast Recognition: Unlocks in under 0.5 seconds thanks to an AI-powered semiconductor biometric chip that learns and improves with every use — works even with dry, chafed, or sweaty fingers.
- App-Connected Security: Manage up to 20 fingerprints, view full unlocking history, set access permissions, add or remove users, and receive real-time unlock alerts — all from your smartphone.
- Ultra-Low False Acceptance Rate: At less than 0.001%, unauthorized access is virtually impossible, while the false rejection rate stays below 1% for seamless authorized entry.
- Long-Lasting Battery: The built-in 120mAh rechargeable lithium battery enters sleep mode automatically when not in use. A single full charge delivers approximately 2,000 unlocks.
- Low Battery Alert: The indicator light flashes red four times after an unlock attempt to warn you when the battery is running low — so you're never caught off guard.
- Rugged Build: Zinc alloy lock body and alloy steel shackle (4.5mm diameter) provide robust protection against tampering, cutting, and corrosion.
