Abstract

The device of the present invention is a stand alone radio frequency identification (RFID) reader/writer device comprising a micro controller having non-volatile data memory, an RFID module, at least one input/output port, and a display. The device of the present invention is fully configurable and may serve as a multi-functional transaction sentry, i.e., a ticket taker, a money or point collector, a money or point dispenser, an access controller, a balance inquiry station, a transaction logger, etc. The method of the present invention comprises steps for configuring, operating and collecting data from the RFID reader/writer device of the present invention. The configuration, operation or data collection from the RFID device of the present invention may be performed by using either the RFID module or the at least one input/output port.

Claims

1. A method of operating a stand-alone radio frequency identification reader/writer device having an RFID module and non-volatile data memory, comprising the steps of:

placing a user card having a user ID and user data, in close proximity to the RFID module;

reading and verifying the user ID;

displaying results of the reading and verification of the user ID;

reading and processing the user data;

displaying results of the reading and processing of the user data;

storing, in the non-volatile data memory, transactional data about the reading and processing of the user data;

displaying a ready notification for reading of the next user card on the reader/writer device; and

collecting the transactional data from the non-volatile data memory.

2. The method of claim 1, wherein the initializing step comprises the steps of:

presenting a configuration program having a configuration ID and configuration data, to the stand-alone radio frequency identification reader/writer device;

reading and verifying the configuration ID;

displaying results of the reading and verification of the configuration ID;

reading the configuration data;

writing the configuration data to the non-volatile data memory;

verifying the configuration data written to the non-volatile data memory; and

displaying results of the reading, writing and verification of the configuration data.

3. The method of claim 2, wherein presenting a configuration program comprises placing an RFID configuration card having a configuration ID and configuration data in close proximity to the RFID module.

4. The method of claim 2, wherein presenting a configuration program comprises connecting a configuration device having a configuration ID and configuration data to an input/output port on the reader/writer device.

5. The method of claim 2, wherein the initializing step further comprises the step of restarting the initialization step until the verification of the configuration ID is positive prior to reading the configuration data.

6. The method of claim 2, wherein the initializing step further comprises the step of restarting the initialization step until the verification of the configuration data is positive prior to displaying the results of the reading, writing and verification of the configuration data.

7. The method of claim 6, wherein presenting a data collection device comprises placing a data collection card having a data collection ID in close proximity to the RFID module.

8. The method of claim 6, wherein presenting a data collection device comprises connecting a data collection device having a data collection ID to an input/output port on the reader/writer device.

9. The method of claim 6, wherein the collecting step further comprises the step of restarting the collection step until the verification of the data collection ID is positive prior to writing the transactional data to the data collection card.

10. The method of claim 6, wherein the collecting step further comprises the step of restarting the collection step until the verification of the transactional data written to the data collection device is positive prior to marking the transactional data.

11. The method of claim 6, wherein the collecting step further comprises the step of printing the transactional data from the non-volatile data memory prior to marking the transactional data.

12. The method of claim 11, wherein the initializing step further comprises the step of restarting the initialization step until the verification of the configuration ID is positive prior to reading the configuration data.

13. The method of claim 11, wherein the initializing step further comprises the step of restarting the initialization step until the verification of the configuration data is positive prior to displaying the results of the reading, writing and verification of the configuration data.

14. The method of claim 11, wherein the collecting step further comprises the step of restarting the collection step until the verification of the data collection ID is positive prior to writing the transactional data to the data collection card.

15. The method of claim 11, wherein the collecting step further comprises the step of restarting the collection step until the verification of the transactional data written to the data collection card is positive prior to marking the transactional data.

16. The method of claim 11, wherein the collecting step further comprises the step of printing the transactional data from the non-volatile data memory prior to marking the transactional data.

17. The method of claim 11, further comprising the step of pausing for a configurable duration of time prior to displaying the ready notification.

18. The method of claim 11, further comprising the step of printing a hard copy printout of the results of the reading and processing of the user data prior to displaying the ready notification.

19. The method of claim 11, further comprising the step of printing a receipt showing the results of the reading and processing of the user data prior to displaying the ready notification.

20. The method of claim 1, wherein processing the user data comprises the steps of:

analyzing and modifying the user data;

writing the modified user data to the user card; and

verifying the modified user data written to the user card.

21. The method of claim 1, wherein the collecting step comprises the steps of:

presenting a data collection device, having a data collection ID, to the stand-alone radio frequency identification reader/writer device;

reading and verifying the data collection ID;

displaying results of the reading and verification of the data collection ID;

writing the transactional data to the data collection device;

verifying the transactional data written to the data collection device;

displaying results of the writing and verification of the transactional data; and

marking the transactional data in the non-volatile data memory.

22. The method of claim 1, further comprising the step of pausing for a configurable duration of time prior to displaying the ready notification.

23. The method of claim 1, further comprising the step of printing a hard copy printout of the results of the reading and processing of the user data prior to displaying the ready notification.

24. The method of claim 1, further comprising the step of printing a receipt showing the results of the reading and processing of the user data prior to displaying the ready notification.

25. A method of operating a stand-alone radio frequency identification reader/writer device having an RFID module and non-volatile data memory, comprising the steps of:

initializing the stand-alone radio frequency identification reader/writer device by, placing a configuration card having a configuration ID and configuration data, in close proximity to the RFID module, reading and verifying the configuration ID, displaying results of the reading and verification of the configuration ID, reading the configuration data writing the configuration data to the non-volatile data memory, verifying the configuration data written to the non-volatile data memory, and displaying results of the reading, writing and verification of the configuration data;
