Combination check and credit card sales slip

Abstract

A package of preprinted forms includes one form printed on one side as a conventional bank check, and on the reverse side as a conventional credit card sales slip. Overlying the sales slip printed side of this first form is a second form, printed as a corresponding credit card customer receipt form. Carbon is provided between the two forms to transfer writing from the receipt to the sales slip on the reverse side of the check. A protector between the forms prevents writing on the check side from being unintentionally reproduced on its reverse, sales slip side.
