## 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

### Claim 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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the command includes a code value identifying a type of the command.

### Claim 3 (depends on 1)

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.

### Claim 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.

### Claim 5 (depends on 4)

The reading device of claim 4, wherein the command includes a code value identifying a type of the command.

### Claim 6 (depends on 4)

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.
