Why carry a card when you can buy stuff with the flick of the wrist. Two theme parks in Atlanta have begun using wireless wristbands to enable visitors to pay for merchandise and refreshments, as well as to gain access to parks, individual rides, and lockers. The “Smart Bands”, produced by San Fernando, CA-based Precision Dynamics, is being used by Stone Mountain Park and Six Flags Over Georgia. The “Smart Band” incorporates radio frequency identification technology from Texas Instruments. Precision Dynamics has also implemented its “Smart Band” technology at Six Flags Over Georgia in a “Floating Locker System” developed by Compusafe Electronic Locker Systems of Wentworth Falls, Australia. Guests purchase their “Locker Band” for the day and the new RFID-based system lets them rent a locker on demand at any of the park’s lockers for just the time they need it. Each “Locker Band” is equipped with TI’s “Tag-it” smart label inlay, which individually identifies each patron and allows data to be written to and read from the bands to control access to the lockers. Precision Dynamics introduced the first patient bar code ID wristband in 1984 and RFID wristbands in 2000.
