Abstract: An encoded data card unit apparatus includes a first unit side and an opposed second unit side coextensive with the first unit side, and also includes a case unit. A card-mounted first data-encoded magnetic stripe is mounted on the first unit side adjacent to a straight first card unit edge. A card-mounted second data-encoded magnetic stripe is mounted on the first unit side or on the second unit side adjacent to a straight second card unit edge. The first card unit edge and the second card unit edge are substantially perpendicular to each other. The first unit side and the second unit side are non-rectangular in shape. The card unit and case unit can include a number of devices or applications to protect data, and reduce fraud or identity theft.

Abstract: A non-quadrilateral data-encoded card is provided having a partially circular shape with a substantially straight edge portion. A data-storage region is disposed on one side of the card substantially parallel to but spaced from the straight edge portion. A case for the card is formed from first and second cover portions. The first and second cover portions are pivotally connected to each other and to the card. As a result of the pivotal connection, the card may be pivotally accessed easily relative to the first or second cover portions. The card with its uniquely shaped partially circular peripheral extent and straight edge portion has application as a credit card, debit card, gift card, or other value associated card.
