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 RPM reader and the RFID reader control unit.

Claims

1. A method for setting a parameter, the method performed by a reading device and comprising:

receiving, from a mobile processor, a command including a plurality of setting parameters; and

setting a select parameter for selecting at least one of a corresponding tag device based on the received plurality of the setting parameters,

wherein the plurality of the setting parameters include at least a section indicating field, a start address field, a length field, and a comparison value, and

wherein the section indicating field specifies an specific memory area of the tag device, the start address field specifies a start point of the specific memory area of the tag device, the length field specifies a length from the start point, the comparison value includes a bit to be compared with a target value stored in the tag device, the target value extracted from the specific memory area using the start address field and the length field.

2. The method of claim 1, wherein the command includes a code discerning a type of a command.

3. The method of claim 2, further transmitting a response message in response to the received command, the response message including the code included in the received command, when the received command is performed successfully.

4. The method of claim 3, wherein the command and the response message operate in pairs.

5. The method of claim 2, further storing a result code indicating a reason of failure when the command is failed.

6. The method of claim 1, further transmitting a select command including the set select parameter to the tag device.

7. A reading device, comprising:

an interface unit configured to transmit/receive data to/from a mobile processor;

a control unit configured to;

receive, from the mobile processor via the interface unit, a command including a plurality of setting parameters, and

set a select parameter for selecting at least one of a corresponding tag device based on the received plurality of the setting parameters,

wherein the plurality of the setting parameters include at least a section indicating field, a start address field, a length field, and a comparison value, and

wherein the section indicating field specifies an specific memory area of the tag device, the start address field specifies a start point of the specific memory area of the tag device, the length field specifies a length from the start point, the comparison value includes a bit to be compared with a target value stored in the tag device, the target value extracted from the specific memory area using the start address field and the length field.

8. The reading device of claim 7, wherein the command includes a code discerning a type of a command.

9. The reading device of claim 8, wherein the control unit further transmits a response message in response to the received command, the response message including the code included in the received command, when the received command is performed successfully.

10. The reading device of claim 9, wherein the command and the response message operate in pairs.

11. The reading device of claim 8, wherein the reading device further stores a result code indicating a reason of failure when the command is failed.

12. The reading device of claim 7, wherein the control unit further transmits, via the interface unit, a select command including the set select parameter to the tag device.
