ABSTRACT:
A thin label consisting of a geometric matrix (1) which is applied, embedded, programmed or printed on to the surface of a bank or credit card (2) for the purpose of recalling the specific Personal identification Number (PIN). A sequential pattern is chosen within the matrix. The PIN is installed into the sequential pattern in a predetermined order. The remaining empty spaces within the matrix are filled-in with other numbers or characters to render the PIN encoded. The authorized user of the credit card need only recognize the sequential pattern within the matrix to recall the specific PIN. Other credit card PINs can be recalled by utilizing the same sequential matrix pattern to encode the different PINs. By recognizing a single sequential pattern within the matrix, the user can recall a multitude of PINs without jeopardizing the intended security associated with PIN use.
