ABSTRACT:
A graphical interface for a credit card authorization terminal. In a first embodiment of the present invention, the data transmission between the credit card authorization terminal and the receipt printer is monitored for the occurrence of a search data string containing the name of the retail establishment. Once located, the search data string is edited from the data transmission and a replacement data string is inserted. The replacement data string contains control and/or data words which cause the graphical logo of the retail establishment to be printed on the credit card receipt. In a second embodiment, the credit card authorization terminal is programmed to transmit the graphical command and/or data words directly to the receipt printer.
