I want to make an android app that easily connects to off-the-shelf USB fingerprint scanners. I am not sure if the android.hardware.fingerprint supports externally connected devices. Or is it only for internal scanner? Can anybody please confirm?
Edit: I would also like to know, would the USB connected fingerprint scanner work on devices that do not have inbuilt module, or on devices on older Android versions, i.e. 5.1 & below, since native API support has only been added from Android 6.0 onwards.
Guides/tutorials/links etc., anything will do. Please suggest something. Thanks.
