As shown in fig. 1, the employed radio frequency identification chip card conforming to the EPC C1G2 protocol has four memory areas therein, and each memory area may be composed of more than one memory word. These four storage areas are:

EPC zone (EPC): an area storing the EPC number. Can be read and written.

TID zone (TID): an ID number set by the label manufacturer is stored. Readable and non-writable.

User area (User): the zone is different from manufacturer to manufacturer. Can be read and written.

Reserved area (Password): and accessing and destroying the password storage area. Can be read and written.

Four storage areas are write-protected. Write-protected means that the area is never writable or not writable in an unsecured state; read protection only the cipher area can be set as read protection, i.e. unreadable.
