Finger Vein Scanners Edit
Hitachi's High Tech Security

Biometrics seems to be the future of security and payment systems. Although not mainstream yet, fingerprints and retina scans are already being used. Hitachi has developed and is planning to field test the next technology in biometric systems using the veins inside our fingers. Infrared LEDs and a camera scans a person’s finger, checking it against a database (just like fingerprints). Supposedly, finger veins are more secure due to their hard-to-duplicate pattern.
