Abstract
Abstract A carbon security system is provided for a customer using a credit card to get all of the carbons when the customer copy is taken. Security is achieved because all carbons are connected to the customer copy and are removed together with the customer copy. A set made up of the customer copy and all carbons may be folded over so that the carbons are left inside of the folded customer copy. A strip of adhesive attached to the top side or underside of the stub retains the folded set together. Thus, there results a very good way for the customer to retain the carbons without getting a mess on his or her hands and without risking fraudulent use of credit card data obtained from the carbons.
