Abstract
The present invention relates to the technology of recognizing and reading each game chip although game chips are stacked. The present invention is a game chip storing data readable by a reader/writer having an antenna which emits an electromagnetic wave and available in a stack of game chips, and includes: an IC device for communicating data at a request from the reader/writer; an antenna electrode connected to the IC device, and configured such that the antenna electrode can enter a resonant state with an antenna of the reader/writer through an electromagnetic wave; and a reflection member for reflecting an electromagnetic wave reflected from the antenna of the reader/writer toward upper game chips in the stack.
Claims12
A game chip storing data readable by a read device having an antenna which emits an electromagnetic wave, the game chip being available in a stack of other game chips, comprising:
- a circuit for communicating data with the read device in response to a request from the read device;
- an antenna being connected to the circuit, and being configured such that the antenna can enter a resonant state with the antenna of the read device through an electromagnetic wave;
- and
- a reflector for reflecting an electromagnetic wave from the antenna of the read device toward upper game chips in the stack.
