Abstract
In one embodiment, a presentation instrument comprises a card body having machine readable information stored thereon. A protective device is coupled to the card body so as to be disposed over at least a portion of the machine readable information such that the machine readable information is incapable of being read by a machine when the protective device is in place and the machine readable information is readable by a machine when the protective device is removed.
