To provide a merchandise management system for efficiently performing total merchandise management from production to physical distribution, sales and repair.

A communication control part 13 controls an IC chip 1 and signals received in an antenna part 11 are supplied to a radio communication control part 12, processed in the communication control part 13 and sent to an information storage part 14. In the information storage part 14, depending on received data, the data are stored in a global information storage part 141 or a personal information storage part 142. In a coil part 152 inside a power supply part 15, when magnetic force from the outside is supplied, power is generated. The power is controlled in a power control part 151 and sent from he power supply part 15 to the communication control part 13. The power to be used inside the IC chip 1 is supplied from the communication control part 13 to each parts inside the IC chip 1.
