Abstract: A point-of-sale security activation card is provided. The card includes first and second card panels, a security element selectively interposed between the card panels, and machine readable content carried by either or both of the card panels. An inside panel surface of the first card panel is characterized by a revealable information field comprised of revealable information. The second card panel includes a tab, the tab overlying an end portion of the revealable information field of the first card panel. The security element includes a body, and a head extending therefrom. The head underlies the tab of the second card panel, the body overlying a substantial portion of the revealable information and intersecting with the machine readable content. Manipulation of the tab in furtherance of revealing the revealable information results in corruption of the machine readable content by the security element.
