Wireless Sports Technology

DETAILS
A wireless three-dimensional target is on the playing field. A player kicks a ball at the target.

OPERATION
When the ball contacts the wireless target the target logs a score. The score is wirelessly communicated to an electronic scoreboard.

QUESTIONS
1. What wireless technology will log a point only when the ball contacts the target. (If a foot, and not the ball, contacts the target it does not score a point).

Thanks
