RADIO IC TAG, RADIO IC TAG READER/WRITER, AND RADIO IC TAG COMMUNICATION SYSTEM USING RADIO IC TAG AND RADIO IC TAG READER/WRITER

摘要

PROBLEM TO BE SOLVED: To provide a device and a communication system capable of writing and reading data surely even from a relatively long distance to the radio IC tag.;SOLUTION: The radio IC tag communication system includes a reader/writer for reading/writing data by radio communication to the radio IC tag, and the radio IC tag composed by mounting the memory part and the antenna part on a substrate. The reader/writer outputs the radio waves of a first frequency for generating the electricity of the radio IC tag and the radio waves of a second frequency different from the first frequency, for writing/reading the data, the electricity is generated in the radio IC tag by the radio waves of the first frequency, and the data are written/read by the radio waves of a second frequency.;COPYRIGHT: (C)2012,JPO&INPIT
