Fingerprint ID Scanner (w/ Key) - Escape Room Prop

Introduction:
The system will deny to access when players put one finger on the fingerprint screen. But if the players find a magic key and use the key to crack the system, they will get the authority to gain access. Players must then put one finger on the fingerprint screen once again - this time the system will accept the fingerprint and the lock will release.

Prop list:
1 fingerprint ID screen system
