I don't know how the store systems are set up. I do know that we have two door lock fingerprint scanners where I work. These scanners apparently store the fingerprint info locally to themselves because I had to have my fingerprint read into each separately. They could not share the scan/image from one to the other. Seemed like a poor setup to me, but it made me less worried about that scanned image getting loose in the world if they could not even transmit the info from one scanner to another of the exact same make and model.
I'm not sure what anyone could do with my scanned fingerprint anyway. If someone could get it out of the scanner on the door lock system they could also get into my office and borrow my coffee cup to get a more complete set. In the case of a store system as we have been talking about, anyone with enough access to get my fingerprint image out of the system could simply charge stuff to my account directly anyway. I suppose someone could frame me for a major crime with my fingerprint, but I can't imagine who would go to all that bother or why.
