WIRELESS TAG WRITING/READING APPARATUS AND METHOD BY THE SAME
First Claim
1. A wireless tag writing apparatus comprising:
- a generation unit configured to generate an identification code to be written in a wireless tag having a memory storing data, the identification code identifying an object attached with the wireless tag;
an adding unit configured to calculate the identification code according to a determination type code representing a type of a determination method for confirming whether there is any garbled bit occurring in the identification code, and add a generated check code resultant from calculation according to the determination method to the identification code; and
a communication unit configured to communicate with the wireless tag, and write the identification code, the determination type code, and the check code to the memory of the wireless tag.

9. A wireless tag reading apparatus comprising:
-
a communication unit configured to communicate with a wireless tag having a memory storing data, and read information from the memory; a reading unit configured to read, from the wireless tag by received data of the communication unit, an identification code for identifying an object attached with the wireless tag, a determination type code representing a type of a determination method for confirming whether there is any garbled bit occurring in the identification code in the memory, and a first check code resultant from calculation by the wireless tag generated from the identification code according to the determination type code; a generation unit configured to generate a second check code from the identification code read from the reading unit, on the basis of the type represented by the determination type code read by the reading unit; and a determination unit configured to determine correctness of the identification code by comparing the second check code generated by the generation unit and the first check code read by the reading unit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A data writing/reading method performed by a wireless tag writing/reading apparatus, comprising:
-
specifying a type of a determination method for confirming whether there is any garbled bit occurring in the identification code for identifying an object attached with the wireless tag having a memory storing data; generating a check code from the identification code on the basis of the specified type; adding the determination type code representing the specified type and the generated check code to the identification code, and transmitting the identification code, the determination type code and the check code to the wireless tag; reading a first check code corresponding to the identification code, the determination type code, and the first check code in the memory from the wireless tag; generating a second check code from the read identification code on the basis of the determination type represented by the read determination type code; and determining correctness of the identification code by comparing the generated second check code with the read first check code. - View Dependent Claims (18, 19, 20)
