を特徴とする物品識別システム。[Claims for Utility Model Registration] A memory for holding data, a memory control means for controlling writing and reading of data into the memory, demodulating commands and data given from the outside, and supplying the demodulated data to the memory control means for reading. a data carrier attached to an article to be identified; and a data transmitting means for transmitting data to the data carrier and receiving the sent data. An article identification system comprising: a write/read control unit; and a write protect determination means for determining whether or not a transfer source data carrier is write protected; write protection canceling means for reading data from the source data carrier and transferring the data to the destination data carrier; and write protection for attaching write protection to the destination data carrier based on determination by the write protection determining means. An article identification system comprising additional means.
