FACIAL SCANS

In the wake of the terrorist attacks on September 11, 2001, in the United States, airport security personnel tested out new technologies designed to improve safety measures. One of the methods was a facial recognition system, which scans people's faces and digitally compares the images against those of suspected terrorists. The technology, however, is not new. Some casinos use such devices to identify people who have been known to cheat.
