These days, it is becoming common to have digital fingerprint readers for use as timekeeping devices. Analog bundy clocks are still widely used but biometric fingerprint readers offer an additional advantage in security. They're also good for a few other uses.
Distributors of digital fingerprint readers tend to market them solely as timekeeping devices for the purpose of automatically calculating payroll. Digital Persona seems to have taken the extra step beyond this market limit. Recently, I was able to sell a U Are U 4500 fingerprint reader. Unlike a lot of biometric devices which look a lot like boxes, this is a small device with a USB cable attached to it. This also means that it is permanently attached to a PC. The boxy biometric devices are usually accessible via a LAN or downloading its accumulated data via USB port.
