1. non-contact IC medium communication device is characterized in that comprising:

  • Receiving element, each that reads in the zone for a plurality of differences reads the zone, this receiving element obtain this read region memory the identifying information of contact-less IC media and the signal intensity of the received signal that receives from this contact-less IC media that is associated with this identifying information;

    Arithmetic element, for each above-mentioned identifying information, this arithmetic element is carried out calculus of differences or division arithmetic with the above-mentioned signal intensity that reads the received signal in zone of a plurality of differences, obtains composite signal intensity;

    Extracting unit, this extracting unit extract the above-mentioned identifying information of above-mentioned composite signal intensity in the pre-set threshold scope.
