Abstract

An RFID reader control system and method is provided. A protocol for controlling an RFID reader and an RFID reader control unit of a mobile phone is defined. Messages, information, commands, responses, and notification are constructed and transmitted between the RFID reader and the RFID reader control unit.

Claims

1. A method of reading a data from a tag device, the method performed by a reading device and comprising:

receiving, from a mobile processor by the reading device, a first command including a first value indicating a number of reading cycles;

receiving, from the mobile processor by the reading device, a second command for instructing the reading device to perform a reading operation to read a plurality of tag devices automatically, the second command including a second value indicating a number of repeat cycles;

calculating, by the reading device, a number of the reading operation by multiplying the first value and the second value; and

performing, by the reading device, the reading operation according to the calculated number.

2. The method of claim 1,

wherein the first command includes a first command-code value discerning a type of the first command and the second command includes a second command-code value discerning a type of the second command.

3. The method of claim 2, further comprising

transmitting a first response message in response to the first command;

and

transmitting a second response message in response to the second command.

4. The method of claim 3,

wherein the first response message includes a value the same as the first command-code value included in the first command, when the first command is performed successfully.

5. The method of claim 1, further comprising

storing a result code value indicating a reason of failure when at least the first command and the second command is failed.

6. The method of claim 1, further comprising

stopping the reading operation, when the reading operation is performed by the calculated number or when there is no tag device to be read.

13. The method of claim 1, wherein the first command further includes delay time information that represents a delay between read operations.

14. The method of claim 1,

wherein the second command further includes a first code value and a second code value,

wherein the first code value instructs the reading device to perform the automatic read operation, and

wherein the second code value indicates which memory part of which type of a tag device is to be read in the automatic read operation.

15. The method of claim 1, wherein the second command does not include an address of a tag device to be read in the automatic read operation.

7. A reading device configured to read data from a tag device, the reading device comprising

a first interface unit configured to transmit/receive data to/from an external module;

and

a control unit configured to;

receive, from the external module via the first interface unit, a first command including a first value indicating a number of reading cycles,

receive, from the external module via the first interface unit, an second command for instructing the reading device to perform a reading operation reading a plurality of tag devices automatically, the second command including a second value indicating a number of repeat cycles,

calculate a number of the reading operation by multiplying the first value and the second value, and

perform the reading operation according to the calculated number.

8. The reading device of claim 7, wherein the first command includes a first command-code value discerning a type of the first command and the second command includes a second command-code value discerning a type of the second command.

9. The reading device of claim 8, wherein the control unit further transmits a first response message in response to the first command and transmits a second response message in response to the second command.

10. The reading device of claim 9, wherein the first response message includes a value the same as the first command-code value included in the first command, when the first command is performed successfully.

11. The reading device of claim 7, wherein the control unit further stores a result code value indicating a reason of failure when at least the first command and the second command is failed.

12. The reading device of claim 7, wherein the control unit further stops the reading operation, when the reading operation is performed by the calculated number or when there is no tag device to be read.

16. The reading device of claim 7, wherein the first command further includes a delay time information that represents a delay between read operations.

17. The reading device of claim 7,

wherein the second command further includes a first code value and a second code value,

wherein the first code value instructs the reading device to perform the automatic read operation, and

wherein the second code value indicates which memory part of which type of a tag device to be read in the automatic read operation.

18. The reading device of claim 7, wherein the second command does not include an address of a tag device to be read in the automatic read operation.
