Abstract

A downloaded app controls a device to recognize whether a connected card reader is an unsupported card reader or whether an unsupported card is supplied to the connected card reader. The app automatically generates support for the unsupported card reader or unsupported card by reading the identifying information from the unsupported card reader or unsupported card, modifying an existing driver support file by adding the identifying information to the existing driver support file to create a modified driver support file, and testing the unsupported card reader or unsupported card using the modified driver support file. If the tests are successful, the app then supplies the modified driver support file to other devices separate from the printer.

Claims (66)

1. A device comprising:

a processor;

functional components operatively connected to the processor;

a user interface operatively connected to the processor;

a connected card reader operatively connected to the processor; and

a computer storage device operatively connected to the processor,

wherein the processor is configured to recognize whether the connected card reader is an unsupported card reader or whether an unsupported card is supplied to the connected card reader,

wherein the processor is configured to automatically modify driver support files in the computer storage device to communicate with the unsupported card reader or the unsupported card by:

reading identifying information from the unsupported card reader or the unsupported card;

modifying an existing driver support file by adding the identifying information to the existing driver support file to create a modified driver support file;

testing the unsupported card reader or the unsupported card using the modified driver support file by:

storing a backup of the existing driver support file before creating the modified driver support file;

deactivating the backup of the existing driver support file and activating the modified driver support file;

facilitating a series of communication and operation tests on the unsupported card reader or the unsupported card using the modified driver support file;

deactivating the modified driver support file and reactivating the backup of the existing driver support file based on tests being unsuccessful; and

keeping the backup of the existing driver support file deactivated based on the testing being successful; and

supplying the modified driver support file to other devices separate from the device based on the testing being successful.

2. The device according to claim 1 , wherein the processor performs the supplying of the modified driver support file to the other devices separate from the device by:

creating a clone file from the modified driver support file; and

sharing the clone file with the other devices separate from the device through a computerized network.

3. The device according to claim 1 , wherein the processor is configured to determine whether to perform the modifying of the existing driver support file based on a similarity measure between the identifying information from the unsupported card reader or the unsupported card and identifying information of card readers and cards that the existing driver support file handles before being modified.

4. The device according to claim 1 , wherein a supported card reader is one identified within at least one driver support file stored within the device, and wherein an unsupported card reader is one not identified within at least one driver support file stored within the device.

5. The device according to claim 1 , wherein the device may only be operated using a supported card reader and a supported card.

6. The device according to claim 1 , wherein the identifying information comprise a vendor identification, a product identification, and an answer to reset (ATR) string of the unsupported card.

7. A system comprising:

a printer having a connected card reader, wherein the printer comprises a computer storage device;

a computer server in communication with the printer through a computerized network; and

a computer application (app) maintained by the computer server,

wherein the computer server is configured to provide the app to the printer,

wherein the app is configured to control the printer to recognize whether the connected card reader is an unsupported card reader or whether an unsupported card is supplied to the connected card reader,

wherein the app is configured to automatically control the printer to modify driver support files in the computer storage device to communicate with the unsupported card reader or the unsupported card by:
