Gotcha! is a two-piece system based on RFID technology and consisting of a clip-on unit that is worn by the child and a second, pager-sized unit that is carried by the parent or guardian. Whenever the naughty child wanders “beyond the adjustable, predetermined safety perimeter”, the system emits an alarm alerting the parent.
“Gotcha! is ideal for use in crowded shopping malls, supermarkets, parks, or anywhere children are prone to wander.”
