For example, when a player interrupts the game, the game history is recorded, and when the game is resumed at a later date, the previously interrupted game situation is reproduced, It is used when the game is continued from that state.

  Also, in some types of video game machines, when a player tries to power up a character or acquire a desired item, it is inserted into the card slot of the game machine to achieve the intended purpose. This type of card is used.

  However, since conventionally known cards are mainly made of synthetic paper or plastic, the surface is smooth and glossy, but there is no metallic luster, and it was not used as a mirror surface.

  In recent near-future game machines, props possessed by characters appearing in games are often used to exhibit strong power by emitting a strong glow or sparkling. However, there is no card that can be used for the player to exhibit or suggest such a function.

  If such a shining prop can be given to the player, the interest of the game can be further enhanced.

Also, with conventional cards, the image data recorded on the IC chip could be read with a card reader and projected onto the screen with a projector, but conventionally the screen was small and could not be said to be very clear. .
It would be advantageous to provide a device that can be enlarged and projected on a screen with a simple device.
