A golf ball has a radio-frequency identification (RFID) circuit for storing ID information therein, the RFID circuit formed of conductive ink; and an antenna for communicating by using radio frequency signals, the antenna connected to the RFID circuit. The antenna may be formed of conductive ink or paste. The RFID circuit and the antenna may be formed on the surface of the golf ball. The golf ball may further include a core layer, a cover layer disposed on the outside of the core layer, and optionally, an intermediate layer disposed between the core layer and the cover layer. The core or intermediate layer has a groove on the surface thereof, and the RFID circuit and the antenna may be formed within the groove.
