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 for performing a specific operation, the method performed by a reading device and comprising:

transmitting a command for performing the specific operation, the command including a code value identifying a type of the command and a plurality of select parameters, and the specific operation being related to a selection of a tag device;

selecting at least one of the tag device based on the plurality of the select parameters; and

transmitting a reading command, the reading command allowing the reading device to read an identifier of the tag device, and the identifier identifying the tag device uniquely,

wherein the plurality of the select parameters include a section field, a start address field, a length field, and a comparison value, and

wherein the section 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 target information, the target information being obtained based on the start address field and the length field.

2. The method of claim 1, wherein the section field include at least one of a unique item identifier, the identifier of the tag device and user-defined memory.

3. The method of claim 1, wherein, when the reading command is successfully performed, a reading response includes a payload field having a variable length.

4. A reading device for performing a specific operation, comprising:

an interface unit configured to transmit/receive data

a controller configured to;

transmit a command for performing the specific operation, the command including a code value identifying a type of the command and a plurality of select parameters, and the specific operation being related to a selection of a tag device;

select at least one of the tag device based on the plurality of the select parameters; and

transmit a reading command, the reading command allowing the reading device to read an identifier of the tag device, and the identifier identifying the tag device uniquely,

wherein the plurality of the select parameters include a section field, a start address field, a length field, and a comparison value, and

wherein the section 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 target information, the target information being obtained based on the start address field and the length field.

5. The reading device of claim 4, wherein the section field include at least one of a unique item identifier, the identifier of the tag device and user-defined memory.

6. The reading device of claim 4, wherein, when the reading command is successfully performed, a reading response includes a payload field having a variable length.
