Android Fingerprint Scanning using Samsung device -

-

am looking write app store fingerprint of people using & later use authenticate them. now, app placed in public place, , there thousands of users. so, need store many fingerprints. tried simple app samsung pass sdk, , samsung tablet fingerprint recognition built in. worked, looks restricting 3 fingerprints only. so, maximum of 3 fingerprints can saved & authenticated with, see. true? possible save thousands of fingerprints & use them in app? or there other company (other samsung) offers capability?

afaik, problem (totally intentional) limitation manufacturer (such samsung, apple...). have done job: prevent biometric data doesn't leave phone. simple that. don't know if there "illegal" method retrieve data work freely it.

maybe can try approach: small device linux (such raspberry pi if don't mind desktop speed) usb fingerprint reader attached
