Abstract
Method for marking a large number of credit cards with unique credit card numbers. A lot size of plastic sheets is selected which is related to the numerical base, b, for expressing the sheet numbers. Each sheet is identically marked with position numbers placed in each of a plurality of uniform credit card areas on each sheet with each area having a position number differing from the position numbers of the other areas on the sheet. Each sheet in the lot is marked with an individual sheet number with sheet numbers being marked by separately marking the individual digits making up the sheet number. After marking the sheets with a digit in the sheet number, the sheets are sorted before marking the next digit. The sorting size is dependent upon the numerical base, b, and the order of the digit which has been marked. After sorting, the sheets in each of the sorted groups have the same distribution of sheet numbers. The next digit is then marked on the sheets and the sheets are again sorted, etc., until all the digits of the sheet numbers have been marked. The sheet numbers are marked in each of the uniform credit card areas on each sheet. At the end of the marking procedure, each credit card area, thus, bears a unique credit card number made up of the position number of the credit card area coupled with the sheet number marked on the particular sheet.
