Abstract

An IC memory card for connecting to a host device connector has a width and a length of substantially standard dimensions, a pair of longer sides, and a connector portion disposed at one of the longer sides and having a connector for electrically connecting the IC memory card to the host device connector. The IC memory card may have a wrong insertion preventing structure for preventing insertion of the IC memory card into the host device connector in an orientation other than the connector portion of the IC memory card. A host device connector for receiving the connector portion of the IC memory card may have a wrong insertion preventing structure for preventing further insertion of the IC memory card by cooperating with the card when the IC memory card is inserted in an incorrect orientation. A connecting system includes the IC memory card and the host device connector including the described features.
