Abstract: PROBLEM TO BE SOLVED: To obtain an improved programming coil by making the coil include mutually coupled plural programming coils generating signals for coupling a general use programmer with tag coils of various constitutions so as to program the tag coils. SOLUTION: The tag coil 12 of a radio frequency identification(RFID) device 10 is provided nearby a programming coil 14. A programming unit 16 sends a signal to the programming coil 14. The programming coil 14 generates a magnetic field for magnetically coupling the programming coil 14 with the tag coil 12 of the RFID device 10. When the programming coil 14 and tag coil 12 are magnetically coupled with each other, the unique sequence of a programming signal is sent by the programming coil 14 and received by the tag coil 12. This programming signal is used to program the RFID device 10.
