<p>PROBLEM TO BE SOLVED: To perform distribution history management or value evaluation by storing history information on a distribution route in a product such as refrigerator or printer so as to perform electronic access. SOLUTION: A recycle chip 2 composed of a non-contact IC card is mounted on a refrigerator 1 and on a non-volatile memory 17 in this recycle chip 2, history information such as production information, recycle information and processing information of the distribution route is written by a reader/writer 21. At the same time, the history information stored on the non-volatile memory 17 is read out and it is confirmed whether the distribution route is proper or not. Then, recycle processing is exactly performed and further, illegal dumping or the like is prevented. Moreover, the time limit of user, residual value evaluation and waste evaluation or the like are calculated on the basis of cumulative using time or fault repair information.</p> |
