Fingerprint scan with ODK

Hello, I want to make a form having finger print scanning capability, such
that the form has a page with button "scan finger print" when pressed
invokes the android device built-in finger-print scanner and records the
user finger print. Kindly guide on how this can be achieved.

@yanokwa , is this option in ODK?

It's not, but if you search for fingerprint, you'll see that it comes up a lot. For this to be considered, it has to be filed at and the use-cases flushed out. One good first step is for you to file that request and link to the various threads over the years...
