Abstract

A system and method for shot tracking is disclosed herein. The system preferably includes a golf club, a receiver device and a server with a website. The golf club preferably includes an active RFID transponder, a power source and a shock switch. When the golf club strikes a golf ball, the shock switch closes thereby powering the RFID transponder which sends a signal to the receiver device for automatically tracking a golfer's round of golf. The data is then uploaded to the website for processing.
