Finger Print Scanner - Firearm Biometric Storage Cable Lock

Good afternoon,

The title kind of speaks for itself. I want to toy around with creating a storage cable lock that is unlocked with my fingerprint. Any ideas on how how to start? Is it possible to repurpose Arduino's sensors for this?

It can be done. If you search you will find articles like this;

People have hacked finger print modules sometimes by literally taking the finger required for operation.
Less messy tricks involve getting a finger print and then using superglue to create a 3D print that can fool scanners.
The biometric people fight back by trying to detect live fingers.

I think it would be worth double checking any false positive and false negative reading rates you are quoted.
