“Each regulation ball contains a tiny radio frequency identification (RFID) tag. If you slice a shot off the fairway into the unknown, you simply pull out a handheld RFID reader, point it in the general direction, and start walking. Once the ball is within the 40-100 foot range of the reader, the embedded tag will respond with an electronic beacon. Then it becomes a hide-and-seek game of “hot/cold” with the scanner beeping faster the closer you get. “
Golfers, break out your tinfoil hats.
