Have you ever bought a season pass to an amusement park for yourself or your kids? You usually make your money back in about two visits. But the hassle is that you have to keep track of the annual pass. If you lose it, you don’t get another one. But Busch Gardens, which has parks in Tampa, Fla., and Williamsburg, Va., has created a solution. The amusement park has started scanning the hands of season pass holders as they enter the park. The technology, called biometrics, reads our unique fingerprints and hand patterns. Biometrics can also read your eye and even your ear print because they each have a unique mapping. Some people are pretty creeped out about this, but it is the wave of the future.
