<P>PROBLEM TO BE SOLVED: To reliably suppress tag forgery and illegal use, and troubles by determining whether a noncontact ID tag is correct or not on the spot. <P>SOLUTION: The noncontact ID tag 10 has light emitting indication parts 11a and 11b at two corners in a diagonal positional relation on an outer surface. A control part 8 of a noncontact ID tag processing device 1 checks ID information transmitted from the noncontact ID tag 10 and received via an antenna 2 against ID information registered in advance in a database 5 to determine whether the received ID information is correct or not, and if it is correct, lights the light emitting indication parts 11a and 11b of the noncontact ID tag 10 having transmitted the correct ID information. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
