Print Scanners Views

In the past few years, however, scanners have started popping up all over the place -- in police stations, high-security buildings and even on PC keyboards. You can pick up a personal USB fingerprint scanner for less than $100, and just like that, your computer's guarded by high-tech biometrics. Instead of, or in addition to, a password, you need your distinctive print to gain access.
Consider scanning a standard 3.5 x5 print, available from a photofinishing lab, with a flatbed scanner. Scanning such a print at 600ppi (within the capacity of current under $300 scanners) yields the same pixel count as scanning a Minox negative at 6927ppi (impossible at this time) or a 35mm negative at 2223 (roughly the resolution of a PhotoCD).
