The biggest RFID card project implementation is going to be in China, where the plastic ID cards issued to Chinese citizens will be replaced by RFID cards. This may be one of the world’s biggest RFID projects, since the Chinese population toady stands at I billion and every man, woman and child will have to be issued one individual card.The estimated value of the project is about 6 billion dollars, truly a large project.Interestingly, the Chinese are not talking about Read only cards and a central database. They are thinking about ID cards with readlwrite capability, biometric information, as well as a magnetic stripe which older card readers can also read. The read/write functionality will be used mostly by police and civic authorities to update information like residential addresses or telephone numbers.
