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.

Claims

1. 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.

2. The electronic funds transfer authorization system of claim 1, wherein:

the search data string comprises a name of a retail establishment; and

the graphical data string comprises data representative of a graphical logo of the retail establishment.

3. The electronic funds transfer authorization system of claim 1, wherein the search data string is deleted from the modified data string.

4. The electronic funds transfer authorization system of claim 1, wherein the interface circuit comprises a microcontroller.

5. 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.

6. The method of claim 5, wherein:

the search data string comprises a name of a retail establishment; and

the graphical data string comprises data representative of a graphical logo of the retail establishment.

7. The method of claim 5, wherein step (c) comprises:

(c.1) deleting the search data string from the modified data string; and

(c.2) inserting the graphical data string into the modified data string when the search data string is located.

8. The method of claim 7, wherein the graphical data string is inserted into the modified data string at a location previously occupied by the search data string.
