ABSTRACT:
An access card, such as a credit card or a key card, having a card body including a plurality of hinged tabs which can be pivoted between a first position in a first plane and a second position in a second plane so that the selected pivoted ones of the tab members in the second position provide a particular coded information for checking the authenticity of a user of the access card. The tab members are arranged in a side-by-side position preferably within a frame member having a partition member disposed between adjacent tab members. Abutment members are provided on the free ends of the tab members opposite the hinged portions, for engagement with abutment portions adjacent thereto, preferably disposed on the frame member, to maintain the selected tab members in the depressed second position even when the access card is longitudinally twisted. The frame member is preferably provided with stop members to prevent the tab members from being depressed beyond the engaged second position with the abutment portions to avoid any damage to the hinged portions of the tab members.
