60. A method for locking a tag device, the method performed by a mobile processor and comprising:
-
transmitting, to a reading device, a reading command, the reading command instructing the reading device to inform an unique identifier of the tag device, the unique identifier identifying the tag device uniquely and the unique identifier having a variable length, wherein the reading device performs a configuring operation of a reading response in response to the reading command, wherein the reading response includes a total length field, a first payload field, and a second payload field, the total length field specifying a total length of the first payload field and the second payload field, the first payload field having a fixed length, and the second payload field having a variable length, and wherein the configuring operation comprises inserting the unique identifier into the second payload field; receiving, from the reading device, the configured reading response; obtaining a unique identifier length by subtracting the fixed length from the total length, the unique identifier length specifying a length of the unique identifier; transmitting, to the reading device, a locking command, the locking command for preventing change of content included in the tag device, wherein the locking command comprises the unique identifier, the unique identifier length, an access password, wherein the reading device obtains the received unique identifier based on the received unique identifier length, wherein the reading device detects the tag device to be locked with the received unique identifier, wherein the reading device accesses to the detected tag device with the received access password, and wherein the reading device locks the accessed tag device for preventing change of content included in the tag device. - View Dependent Claims (61, 62, 63, 64, 65, 66)

67. A mobile terminal for locking a tag device, comprising:
-
an interface unit configured to transmit/receive data to/from a reading device; a processor configured to; transmit, to the reading device via the interface unit, a reading command, the reading command instructing the reading device to inform an unique identifier of the tag device, the unique identifier identifying the tag device uniquely and the unique identifier having a variable length, wherein the reading device performs a configuring operation of a reading response in response to the reading command, wherein the reading response includes a total length field, a first payload field, and a second payload field, the total length field specifying a total length of the first payload field and the second payload field, the first payload field having a fixed length, and the second payload field having a variable length, and wherein the configuring operation comprises inserting the unique identifier into the second payload field, receive, from the reading device via the interface unit, the configured reading response, obtain a unique identifier length by subtracting the fixed length from the total length, the unique identifier length specifying a length of the unique identifier, transmit, to the reading device via the interface unit, a locking command, the locking command for preventing change of content included in the tag device, wherein the locking command comprises the unique identifier, the unique identifier length, an access password, wherein the reading device obtains the received unique identifier based on the received unique identifier length, wherein the reading device detects the tag device to be locked with the received unique identifier, wherein the reading device accesses to the detected tag device with the received access password, and wherein the reading device locks the accessed tag device for preventing change of content included in the tag device. - View Dependent Claims (68, 69, 70, 71, 72, 73)
