Biometric eye scanning. Man (upper right) having his eyes screened by a biometric scanner, which is being used to identify him from his eye patterns. The computer monitor is showing a match between this man and his profile held in the computer's records. The iris, the coloured part of the eye, and the retina, which is inside the eye but is seen though the pupil (black), have unique features in every individual. Other parts of the body used for biometric scanning include fingerprints and the contours of the face. Photographed at the National Physical Laboratory in Teddington, UK.
