Discovery Channel's James Koole takes a look at two companies that use RFID to improve the golf experience.

RadarGolf uses balls with integrated RFID chips to track lost balls. "Besides saving some money by finding those errant shots, the company says it can improve your game by minimizing penalty strokes and speeding up play," Koole writes. "The handheld receiver unit will track down the special balls as long as you're within about 10 to 30 meters. The receiver sports an LCD screen and a pulsing audio tone that will guide you to your missing ball."

TopGolf, on the other hand, uses a similar RFID golf ball to support a unique driving range experience. "Each golf ball is associated with an individual player, and -- using tracking technology built into the range's various target areas -- shots are scored based on accuracy and distance," Koole writes. "Interactive feedback is provided after each stroke on a computer screen at the tee."

The RadarGolf system is now available online -- a complete system with a handheld and a dozen golf balls costs $250. And four TopGolf driving ranges are now open in the U.S. and the U.K., with addition locations planned.
