Game chip

A game chip configured to transmit information in response to an inquiry from a reading device, comprising:

• a circuit unit configured to store the information and constitute an electromagnetic induction coupling circuit with the reading device;
• an antenna unit connected to the circuit unit and configured to generate an induced current by a magnetic flux emitted from the reading device to supply power to the circuit unit when the inquiry is received, and to emit a magnetic flux carrying the information to the reading device when the information is transmitted;
• a first magnetic flux induction unit configured to induce the magnetic flux emitted from the reading device in one of directions of moving away from and approaching the reading device;
• and
• a second magnetic flux induction unit configured to induce the magnetic flux induced by the first magnetic flux induction unit in the other of the directions of moving away from and approaching the reading device.
