PROBLEM TO BE SOLVED: To carry out a highly reliable recognition processing without taking costs even for a production line including a process of bad conditions. SOLUTION: The same information is written to all of a plurality of RF tags 1 and the RF tags 1 are attached to a palette 4 for carrying articles through a supporting holder 6a and carried together with the articles. An antenna 2 successively communicates with the respective RF tags 1, reads the information inside a memory and outputs it to a controller and the controller transmits the information to host equipment further. The host equipment compares the information read from the respective RF tags 1 with each other, and in the case that the majority of the information match, judges that the matching information is appropriate and specifies it as a recognition object. |
