@Mark, thinking outside the box, if one could get a picture of your fingerprint, they can then 3D print a gel with the same, stick it on their fingers and in so doing impersonate you.

Assuming of course, the place where they are impersonating you checks only fingerprints and not the face attached to the fingers.

However, if they additionally had a photo of your face...

At least thats what Mission Impossible AND the tv series Face Off would have me believe.
