Tablet with built-in Authentication

[ChristianSA]

Hi,

This is my first post, so please do not flame me if I am in the wrong forum.

I am looking for an authentication solution for my app running on Android.

Are there any tablets with built-in fingerprint readers and an API for interacting with such a fingerprint reader?

I would also like advice on a tablet manufacturer making tablets that will function in a rough environment (humid).

Thanks in advance,
Christian
