Biometric systems stand guard
The British government has said that iris scans will soon join fingerprinting as a biometric component of immigration checks. Iris scan technology from Germany's Byometric Systems starts out with a black-and-white image of the eye. An algorithm records more than 240 features of the iris and generates a 512-byte reference template that's encoded and stored in a database or on a smart card.
