Review on πŸ”’ HFeng Fingerprint RFID Access Control System Kit with Biometric Door Locks, Electric 180KG Magnetic Lock, Electromagnet, DC12V Power Supply, Exit Button, and 10 Keyfobs Cards – Ideal for Home Door Opener by Alex Montgomery

Revainrating 1 out of 5

EASY to crack in seconds

This lock uses a cheap electromagnetic relay in the fingerprint reader. A magnet that fits in the palm of your hand, which you can buy from Revain for a few bucks, can be placed on the side of the fingerprint reader and triggers a relay which in turn opens the lock in less than 1 second.

Pros
  • Sturdy surface
Cons
  • Crumpled
