Publication number: 20070132549Abstract: A manufacturer of an article generates a keyword, and electromagnetically writes the keyword into an RFID and prints the keyword on a guarantee card. The RFID tag is then affixed to the article, and the article is packed along with the guarantee card and shipped. When making a sale, a retail store hands over the guarantee card to a customer who buys the article. When the customer wishes to sell the article, a purchasing store reads the keyword written to the RFID tag affixed to the article and asks the customer to furnish the keyword. If the keyword furnished by the customer, by referring to the guarantee card, etc., is identical to the keyword read from the RFID tag, the customer is deemed a genuine owner of the article.Type: ApplicationFiled: March 31, 2006Publication date: June 14, 2007Applicant: FUJITSU LIMITEDInventors: Hideki Ichikawa, Makoto Goda, Masaharu Minowa
