Abstract
Abstract A credit card having a row of spaced apart openings formed therein adjacent each of its edges. A slide member is mounted on the card at each of its edges and is adapted to be selectively moved with respect thereto to permit the selective covering of at least one of the openings in the associated row. The card is for use in read-out machines having means therein for passing light or the like through the openings to permit the imprinter to sense where the slide members have been moved to their proper position so that only an authorized person can obtain credit through the use of the card. The proper position of the slide members is known only to the card owner which prevents the card from being used by unauthorized persons.
