Android Question Use fingerprint sensor as reader (not for auth, more than 200 fingerprints)

    I've read some posts about this, but none of them could do exactly what I'm needing:

    I'd need to read fingerprints (around 200 that would be stored in a DB) and check whether they match or not.

    Example: Once I read a fingerprint, I'd check with the DB if it exists. If so, some actions would happen.

    Is it possible with any Android library?

    Thank you in advance

    The android framework for fingerprints only allows a few fingerprints. 5 or so. And only on supported devices.

    I do not know any Library which does give you anything you can store into a db to compare. I only know Fingerprint Authentification which uses the available Android Api.
