Dual Authentication for Maximum Security Electronic Safe Lock with Fingerprint and Password Unlock

1. Dual-Mode Authentication

Fingerprint Unlock

Supports registration of multiple fingerprints (specific quantity subject to product manual, typically 30-100 fingerprints). Recognition speed ≤0.5 seconds, false rejection rate ≤1%, false acceptance rate ≤0.0001%.

Equipped with a biometric capacitive sensor to effectively identify live fingerprints and prevent spoofing attempts.

Password Unlock

Supports 6-12 digit numeric passwords (some models allow dummy password input to prevent shoulder surfing). Correct password entry triggers the door-opening mechanism.

2. Mechanical Linkage Door Opening

Rotary Knob Operation

After successful authentication, manually rotate the circular knob panel to drive the internal mechanical structure, controlling the electromagnetic lock for unlocking.

The knob provides clear tactile feedback and features anti-misoperation design to prevent accidental opening.

3. Power System

Primary Power: 4 AA batteries (approx. 12-month battery life depending on usage frequency). Low battery warning via panel audible alert.

Emergency Power: 9V emergency power interface on the panel allows temporary power supply via external battery case or power bank to address lockout situations.

4. Optimized User Interaction

Illuminated Keypad

Supports touch activation—backlight (typically blue/white LED) automatically illuminates upon wake-up for clear visibility in low-light conditions.

Capacitive touch keys eliminate mechanical wear, with a lifespan ≥100,000 operations.

Status Indication

Provides dual feedback via buzzer tones (e.g., "beep" or "beep-beep-beep") and LED colors (green/red) for successful/failed authentication.
