1. A method for locking a tag device, the method performed by a processor and comprising: transmitting, to a reading device, a reading command,wherein the reading command allows the reading device to read all of a unique item identifier, a tag identifier and a user-defined memory of the tag device;receiving, from the reading device, the reading response including a memory data;transmitting, to the reading device, a locking command, for controlling a lock function for preventing or allowing a writing of a memory bank of the tag device; andreceiving a locking response in response to the locking command,wherein the locking command comprises a unique identifier field and an access password field,wherein the reading device locks the tag device in order to prevent a writing of the memory bank of the tag device, andwherein the locking response includes information for authenticating the tag device when the locking command is performed successfully. 2. The method of claim 1, wherein the reading command and the reading response operate in pairs and the locking command and the locking response operate in pairs. 3. The method of claim 1, wherein the reading command and the locking command include a code value identifying a type of the command. 4.
