On Screen in app fingerprint, does it exist?

First time I am developing an android app, so forgive me, if what I am asking is basic.

In this app, I am building I would like it to take fingerprints on an android tablet, be it on-screen or the button so that it can cross-check against its own fingerprint database to log the person in.

Is this possible?

I moved this to the Galaxy Sensor Extension forum to see if someone could help you there.

If this is not specifically for a Galaxy Tablet then you need to get help in the Android Developer’s forum. There are several of them available as well as example codes in Github

I hope that helps
