| 6. A method of tag grouping, comprising:
storing in a parameter storage medium a parameter which represents a measure of a strength of relationship among a plurality
of ID tags;
increasing and decreasing values of the parameter according to a number of pieces of ID information detected simultaneously
in the plurality of ID tags by a mobile tag reader;
judging the plurality of ID tags as belonging to a same group according to values of the parameter stored in the parameter
storage medium;
when ID information is first detected simultaneously in a pair of ID tags, newly setting the parameter for the pair of ID
tags to indicate the measure of the strength of relationship between the pair of ID tags; and
when ID information is subsequently detected simultaneously in the pair of ID tags, increasing the value of the parameter
stored in the parameter storage medium.
