I am new to fingerprint authentication in smartphones. As we know Samsung S5 currently supports fingerprint scanner. Is it possible to develop a custom application that can use the scanner to authenticate a user? I just need to know the identity of the user and if he has been authenticated correctly. My app can then take it from there and integrate with backend.
Samsung provides Pass API to register, request and validate fingerprints. Its in here SAMSUNG FINGER PRINT API. There is a sample program too.
