Abstract:
1. A method of retrofitting a credit card with an electronically readable region to protect a visibly complete account number comprising the steps: attaching an adhesive mask to the credit card to cover at least a portion of the visibly complete account number thereby providing a card portion displaying only a first part of the account number; inserting the card portion into a sheath portion having imprinted thereon a second part of the account number, wherein the sheath portion is formed with a window through which the first part of the account number is visible, and wherein the first part and second part of the account number provide a complete valid account number; and storing the card portion and the sheath portion together, whereby the card portion is selectively removed from the sheath portion to conduct a transaction via the electronically readable region without the sheath portion, and wherein only the first part of the account number imprinted on the card portion is visible during the transaction which is conducted without releasing the complete valid account number.
