A system and method is provided for entering data from a marked card into a central processing unit and for producing a receipt on which is displayed the entered data in alpha-numeric characters and a unique transaction code in machine readable form. The system utilizes a plurality of dispersed card reader-printers, each with data storage and processing capabilities, in communication with a local terminal on a sequential polling basis. The local terminal is, in turn, in communication with the central processing unit which stores the data read from the cards and assigns the transaction code to it. The system allows the data stored in the CPU to be verified against that read by the card reader-printer and allows the printed transaction code to be verified against that assigned by the central processing unit.

A method of reading, printing and verifying data in a card reader-printer/CPU information processing system comprising the steps of: (a) entering data and storing said data in a card reader-printer, (b) transmitting said data from said card reader-printer to a CPU, assigning a unique transaction code to said data, and storing said data in said CPU along with said transaction code, (c) transmitting said data and associated transaction code from said CPU to said card reader-printer, and receiving said data and transaction code and storing said transaction code in said card reader-printer, (d) comparing said data received by said card reader-printer from said CPU with said data stored in said card reader-printer in step (a), and activating an alarm and terminating further operations if said received data differs from said stored data, (e) producing a receipt on which said data and said transaction code received by said card reader-printer is displayed, and (f) reading said transaction code displayed on said receipt, comparing said read transaction code with said transaction code stored in step (c) and activating an alarm if said read transaction code differs from said stored transaction code.
