Adding finger prints capability(similar to a signature) Survey123

[Jean-YvesLandry1]

In many of our surveys people are often unable to read or write.  On the paper form version we would use an ink pad and fingerprint instead of a signature. I would like the ability to collect fingerprints; at the moment the best method with this application is to take a picture of the ink fingerprint.

Hi Jean Yves,

In terms of scanning equipment, are you referring to the built-in fingerprint sensor of a device (mobile phone) or a dedicated scanning device connected to the phone/computer running Survey123?  If the former, most devices don't allow for programs to access the fingerprint itself- just verify that the fingerprint presented has been registered as the 'user' of the device.

Indeed, It would have to be a dedicated scanning device. Like you mentioned the finger print scanner on most, if not all, devices is not made to be used that way, at least I didn't find anything yet.
