PRIORITY CARD AND METHOD FOR OFFERING PRIORITY ORDER TO SPECIFIC CARD AMONG PLURAL CONTACTLESS CARDS

摘要

PURPOSE: A priority card and a priority order offering method are provided to offer a priority order to contactless cards when they are produced, and to make a card processing terminal preferentially the card with the priority order. CONSTITUTION: The method comprises several steps. Insulated conductive plate or mesh or insulated material is included between card plates in which a card chip and antenna are arranged. An RF(Radio Frequency) field is intercepted for other contactless card which exists at a rear position of the contactless card in which the insulated conductive plate or mesh or insulated material is included in order to offer a priority order to a specific contactless card.
