Finger Print Door Lock

A fingerprint door lock is a biometric security device that uses fingerprint recognition technology to control access to a door. It's a smart alternative to traditional key-based or password-based locks and is commonly used in homes, offices, and secure facilities.

Key Features of Fingerprint Door Locks:

1. Biometric Authentication
   Uses a person’s unique fingerprint to allow access—much harder to duplicate than keys or PINs.

2. Keyless Entry
   No need to carry physical keys—just place your finger on the scanner to unlock.

3. Multiple User Access
   Can store dozens (sometimes hundreds) of fingerprints for family members, employees, or trusted individuals.

4. Access Logs (in Smart Models)
   Tracks who accessed the door and when—useful for monitoring.

5. Multi-Mode Unlocking
   Many models support multiple methods like:

   • Fingerprint

   • PIN code

   • RFID card

   • Mobile app (Bluetooth/Wi-Fi)

   • Mechanical key (as backup)

6. Battery Powered with Emergency Options
   Usually battery-operated and give low-battery alerts. Some have USB emergency power input if the battery dies.

7. Security Features

   • Anti-peep PIN (for entering codes discreetly)

   • Auto-lock function

   • Alarm for forced entry or door left open

Pros

• Highly secure and convenient

• No lost keys or forgotten codes

• Fast unlocking

Cons
