My HP laptop has a fingerprint scanner built in (great feature, by the way. Very quick to log on).
I've noticed this behavior twice:
After about a year, the fingerprint scans become less reliable. I must scan 2-3 times before it recognizes my fingerprint.
I redo the initial learn-my-fingerprint scan, and, bingo, it becomes totally reliable again. Reads the scan first time, every time from then on.
My conclusion is that my fingerprints change. Certainly not enough to go on a crime spree, but enough to matter to the computer.
