POSITION DISPLAY METHOD FOR RADIO TAG

PROBLEM TO BE SOLVED: To solve a problem that a radio tag must avoid interference with the information on others by making read output small and a read position must be accurately and easily known. SOLUTION: A mark 11 showing the position on the radio tag is put on a seal 10 on which a bar code 12 or a sign equivalent to the bar code is printed or the mark 11 is printed together with the bar code 12 or the sign equivalent to the bar code at a position where the radio tag is arranged. Then, a label with the bar code or the sign equivalent to the bar code is stuck to the surface position of a box in which a product with the radio tag is packed corresponding to a part where the radio tag is mounted inside. A bar code reader and a radio tag reader can both be used in the same way as in the conventional manner, and the method is easily fit sensuously. COPYRIGHT: (C)2004,JPO&NCIPI
