Adding your fingerprint is very simple and very similar to how you add fingerprints on a phone. Simple use the provided tool to press the set button, then place the desired finger onto the pad, then remove and replace it in slightly different positions 4 times. The first 3 fingerprints added will be admin fingerprints, you will require an admin fingerprint to add any fingerprints in future.
We recommend that you register multiple fingers/thumbs per user to ensure you have multiple options if one doesn’t recognise.
