Following up on a recent post about RFID wristbands used in waterparks, here’s a similar story showing how RFID will Help Johnny Find Mommy.

The SafeTzone will allow patrons to step up to a kiosk, wave the wristband near a reader, and an electronic map of the venue will appear. The map is configured using simple coordinates which enable a person to quickly find where in the park others are located.

The watchlike plastic bracelet, which holds the active RFID chip, transmits a signal every 12 to 15 seconds. At Wannado City, 42 RF readers search for the signal as visitors walk through the firehouse, the hospital, and other play areas where children ages 4 to 11 can explore a world where they become doctors, dentists, firefighters, actors, television news reporters, and airplane pilots. Each antenna creates its own zone. Most zones in the park are about 100 feet.
