From what I understand, the OS controls all fingerprint data from a device's scanner. I'm building an application where I need to be able to store fingerprint data for a number of users to authenticate them on jobsites, so I won't be able to manage fingerprints through the device only.
Is there any other option for me to implement fingerprint authentication in Xamarin? I've looked into fingerprint.com/fingerprintJS but they don't have support for Xamarin applications at the moment.
