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.
Claims8
An electronic funds transfer authorization system, comprising:
- an electronic funds transfer authorization terminal operable to obtain authorization for an electronic funds transfer transaction and to generate a textual data string operable to cause a printing device to print a textual electronic funds transfer receipt;
- an interface circuit coupled to the electronic funds transfer authorization terminal for reception of the textual data string, wherein the interface circuit is operable to search the textual data string for a predetermined search data string and to modify the textual data string by inserting a predetermined graphical data string into the textual data string when the search data string is located thereby creating a modified data string operable to cause a printing device to print a textual and graphical electronic funds transfer receipt;
- and
- an electronic funds transfer receipt printer coupled to the interface circuit for reception of the modified data string, wherein the modified data string is used to control a single print head within the receipt printer to print both textual and graphical symbols on the electronic funds transfer receipt.
A method of providing a printer interface for an electronic funds transfer authorization terminal, comprising the steps of:
- (a) receiving a textual data string from the authorization terminal, wherein the textual data string is operable to cause a printing device to print a textual electronic funds transfer receipt;
- (b) searching the textual data string for a predetermined search data string;
- (c) modifying the textual data string by inserting a predetermined graphical data string into the textual data string when the search data string is located thereby creating a modified data string operable to cause a printing device to print a textual and graphical electronic funds transfer receipt;
- and
- (d) transmitting the modified data string to an electronic funds transfer receipt printer, wherein the modified data string is used to control a single print head within the receipt printer to print both textual and graphical symbols on the electronic funds transfer receipt.
