Abstract: A device is provided for determining if one or more golf clubs are missing from a group of golf clubs. The device includes a transmitter or transceiver, that is, operative to direct a signal towards a group of golf clubs where each golf club is provided with a sensor tag. The signal from the transmitter registers with the respective sensor tags and in response thereto each sensor tag emits a response signal that is uniquely associated with the sensor tag and the golf club associated with the sensor tag. This response signal is directed back to the transceiver and the transceiver is in return coupled to a controller that receives information or data from the transceiver that identifies the detected golf clubs of the group. Based on the golf clubs detected, the controller can determine if one or more golf clubs are missing from the group.
