You asked, "Would a faxed copy of a fingerprint card be an adequate source for comparison?"
It could be, if sufficient quantity and quality (clarity) of friction ridge detail is represented in the fax image. Many agencies enlarge fingerprint images before faxing to overcome the spatial resolution problems of faxes. (Think of spatial resolution as the relationship of film grain to the details you are trying to see in a photograph.) Special fax equipment and software can also be utilized to increase the resolution.
Some agencies refuse to make an identification from faxed images, but might make an elimination, i.e., say something is non-ident if they see all whorl patterns and the comparison image is an arch pattern.
Digital images sent/retrieved via computer networking is far superior to faxed images.
