Yeah, it does lots of fancy stuff. The biometric ability seems to have a floor price of $20, at least based on a quick amazon search: https://www.amazon.co.uk/usb-fingerprint-reader/s?k=usb+fingerprint+readerhttps://www.amazon.co.uk/usb-fingerprint-reader/s?k=usb+fingerprint+reader

If building / using a thing like this one might consider having backup in some sort of other kind of device that don't require the biometric, just for cheaper backups.
