Can we use the fingerprint to verify with third part API? #138

I am building an application where we will confirm the authenticity of use via fingerprint with our record of fingerprints. Can we perform that while using this package?

Unless I read all the documentation wrong, the actual biometric information (the real fingerprint) is one-way stored on the device, and all we are doing is asking the hardware to compare, we have no access whatsoever to the biometric data, only comparison results.

If I'm wrong, I'd love to know because we potentially have this use case as well but I'm not aware of a way to satisfy it

I believe this is similar to https://github.com/hieuvp/react-native-fingerprint-scanner/issues/54 can you take a look at that discussion and see if it answers the question?
