Abstract: Apparatus for embossing and imprinting information on credit card sales slips in a manner compatible with fully automatic data processing, including a movable magnetic read head mounted to an embossing mechanism for reading the customer information from a magnetic stripe on the credit card during the embossing operation, and means for temporarily storing the information. An impact printer movably mounted below the sales slip pack is positioned to imprint the complete transaction information in a form compatible with existing automatic character recognization apparatus. The reverse side of the credit card issuer's copy of the credit card sales slip is printed with scannable print font setting forth the customer's identification, merchant's identification, sale amount, transaction date, etc., so as to be automatically readable by existing optical character recognition (OCR) or magnetic ink character recognition (MICR) apparatus.
