Description

  The present invention relates to a contactless authentication system, and more particularly to a contactless authentication system that transmits and receives data while supplying power to a recording medium such as a card or a tag from a reader / writer without contact.

  Conventionally, this type of contactless authentication system has been developed. In the conventional contactless authentication system, when there are a plurality of specific cards in the transmit / receive area, the question data is transmitted from the reader / writer to each one of the cards in order, Response data is received from the IC card. The presence / absence of the card is determined by receiving the response data (see, for example, Non-Patent Document 1).

  In the said nonpatent literature 1, when the response data from a card | curd cannot be received, it determines that the card | curd does not exist in the area which can be transmitted / received in all cases. For this reason, it is determined that the card does not exist, even if it does not really exist or if the response data cannot be transmitted because the card is damaged.

  When a non-specific card is present in the transmission / reception area instead of the specific card, response data from the non-specific card is received.

  Also, even within the transmission / reception area, when a wall or the like exists in the vicinity of the IC card and the card cannot receive the question data due to interference, the IC card cannot transmit the response data. It is determined that it does not exist in the transmission / reception area.
