Claims6
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.
