<P>PROBLEM TO BE SOLVED: To provide a system for providing purchase information allowing a customer even at his home to easily use commodity information stored in a radio IC tag affixed on a commodity. <P>SOLUTION: In a radio IC tag 2 affixed on a commodity 3, commodity information 20 on a selling price, a commodity name and the like is stored. A POS terminal 1 uses a radio IC tag reader 11 to read the commodity information 20 from the radio IC tag 2 affixed on each commodity 3, and processes the read commodity information 20 to generate purchase information 12 indicating that a customer has bought the commodity 3. Then, the POS terminal 1 uses an IC card reader 10 to store the generated purchase information 12 in an IC card 5 carried by the customer. The customer uses an IC card reader 60 provided on a PC 6 at his home to read the purchase information 12 stored in the IC card 5, and thus uses the purchase information 12 on the PC 6. <P>COPYRIGHT: (C)2007,JPO&INPIT |
