Kyodo News said the system features the issuance of a radio frequency identification, or RFID tag, to each drivetrain part die, containing information on the die’s status, location, repair record and usage history.


By placing the tag in a special RFID tag reading tray, workers can instantly read information on the die on a nearby computer screen.


As the system uses a stacked reading capacity, information stored on 100 RFID tags can be shown on the screen within two seconds.


Kyodo News said Nissan will test the world’s first system of its kind at its Yokohama plant near Tokyo in the next six months, expecting to improve the efficiency of its drivetrain parts die management.


The system is also expected to help the automaker reduce its die inventory by half to 3,500 units in 2007.


Following the six-month trial to verify the effectiveness of the system, Nissan and NTT DoCoMo, Japan’s largest mobile phone operator, plan to enhance the system’s functions to include process production management of engine parts and the automatic ordering of dies, Kyodo News said.
