Description

  The present invention relates to a non-contact IC card in which an inlet mounted with an IC chip and an antenna is laminated.

  2. Description of the Related Art In recent years, game devices have been widely used in amusement facilities and the like to arrange game cards on a play table and play against on-line opponents. On the front side of the game card used in the game device, a picture and ability value of the game character corresponding to the game card are printed, and a player who plays the game device selects a game card to be arranged on the play table of the game device, Compete for winning or losing tactics by arranging the selected game cards.

  A game device that uses a game card needs a function of recognizing the game cards arranged on the play table of the game device. As a method for recognizing the game cards arranged on the play table, an optical code such as a one-dimensional barcode, a two-dimensional barcode, or a color code identified by color is printed on the game card, and the game card is in contact with the play table. Optically reading a printed optical code is generally used (for example, FIG. 5 of Patent Document 1). The surface on which the optical code is printed is not limited to the back side of the game card. If the optical code is printed on each of the front and back sides of the game card, both sides of the game card can be used for a card game, and the game content can be expanded.

  On the other hand, since the optical code is generally fixed, the game card on which the optical code is printed has a problem that it is not suitable for a card game in which a game character grows as the game progresses. There is also a problem that unauthorized play is possible by altering the optical code printed on the game card.

  Therefore, an attempt to replace the game card with a non-contact IC card has been made as a technique to replace the optical code (for example, Patent Document 2). If the game card is converted into a non-contact IC card, the card information stored in the game card converted into the non-contact IC card can be overwritten in accordance with the progress of the card game, and the card game where the game character grows can be taken. Further, if a password is set for access to card information stored in a non-contact IC card game card, the card information can be prevented from being falsified. In addition, it is possible to obtain a merit that a card game corresponding to a game card can be played even on a device (smart phone or handy type game machine) other than a game device installed in an amusement facility.

  A plurality of reader / writers that wirelessly communicate with a non-contact game card are arranged on a play table of a game device that uses a game card converted to a non-contact IC card (for example, FIG. 3 of Patent Document 2). The position on the play table where the non-contact game card is placed is specified from a reader / writer capable of wireless communication with the game card.

  Even in the case of using a non-contact IC card game card, it is necessary for some card games to be able to recognize whether or not the front side of the game card is face up. In the invention, three IC chips are mounted on the game card, and it is recognized from the intensity of the radio wave transmitted by the IC chip whether or not the front surface of the game card is faced up.

  However, in the invention disclosed in Patent Document 2, the game card transmits the same data wirelessly regardless of whether or not the front side is facing up, so the front side is facing up. If the game device does not have a function for recognizing whether or not, the front of the game card cannot be recognized or not. Outside the game field, if the front and back sides of the contactless IC card can be used properly, it can be used in various solutions. Therefore, in the present invention, the front side is facing forward and the front side is back. An object of the present invention is to provide a non-contact IC card in which data transmitted wirelessly differs depending on when it is facing.

  The present invention for solving the above-mentioned problems is a non-contact IC card in which an inlet having an IC chip and an antenna mounted thereon is laminated, wherein the two inlets are laminated with an electromagnetic wave shielding layer shielding radio waves interposed therebetween. It is a non-contact IC card.

  The non-contact IC card according to the present invention has two inlets stacked with an electromagnetic wave shielding layer that shields radio waves, so that the front side is facing front and the front side is facing back. Depending on the time, the data transmitted wirelessly is different.
