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 controlling a parameter, the method performed by a reading device and comprising:

transmitting a command related to a selection of a tag device, the command including a plurality of select parameters; and

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

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 command includes a code value identifying a type of the command.

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

4. A reading device for controlling a parameter, comprising:

an interface unit configured to transmit/receive data

a controller configured to;

transmit a command related to a selection of a tag device, the command including a plurality of select parameters; and

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

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 command includes a code value identifying a type of the command.

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