I am building an attendance application with React Native. The students will have to indicate their presence in school by scanning their thumbprint. I have seen several libraries that utilize the Android and iOS fingerprint scanners but none has support for CryptoObject where I can access the Asymmetric keys generated when the user scans their fingerprint and I can save it to a server like Firebase.
I finally found the solution, so I think I should drop it here.
This library solved it for me. Very resourceful
