Abstract
A credit card and charge slip are provided which resist credit card fraud. The credit card has auxiliary characters and corresponding dates at which each should be used, the auxiliary characters not being embossed at a copy area as are the numbers of the credit card. A merchant finalizes a credit card purchase by writing the auxiliary character only on the bank copy of the credit slip. The credit slip can be formed with aligned holes in all of the sheets except the bank sheet, so a merchant can write the auxiliary character directly on the bank sheet without even partially separating the sheet.
