Is it doable to collect user fingerprint with android? Our backend system has a fingerprint database. We\'d like to match the fingerprints collected against database to see
I haven't tried this yet, but recent Android OS (Marshmallow) has ability to do that.
"To authenticate users via fingerprint scan, get an instance of the new FingerprintManager class and call the authenticate() method. Your app must be running on a compatible device with a fingerprint sensor. You must implement the user interface for the fingerprint authentication flow on your app, and use the standard Android fingerprint icon in your UI. The Android fingerprint icon (c_fp_40px.png) is included in the Fingerprint Dialog sample. If you are developing multiple apps that use fingerprint authentication, note that each app must authenticate the user’s fingerprint independently. "
