From what I have read about RFID devices, the "chip" only contains a very long unique-in-the-universe "serial number". It does not contain your name or address or blood type or bank balance. The unique serial number must be used in conjunction with a database somewhere. The serial number points to records in the database where the data is stored, and can be easily updated. You typically cannot write data to an RFID chip, and the serial number is "hard wired" at the time of manufacture.
