Ideas of questionable quality

I figured touching them someone used technology to steal their DNA and replicate the fingerprints, so even if they have gloves you can still get it

It'd work on any touch, so helping someone up who slipped would be a good way.

Maybe it could require multiple touches to fully replicate them, so you'd have to tap them 3 to five times or else it only gives partial information

I like the gloves idea but they would also have to be insulated otherwise no one would buy them
