Abstract:
A near field communication device and a method of determining the position of a tag are provided. The near field communication device includes a first coil, a second coil, and a control circuit. One end of the first coil is coupled to a first grounding end. One end of the second coil is coupled to a second grounding end. The control circuit includes a first current pin and a second current pin. The first current pin is coupled to the other end of the first coil. The second current pin is coupled to the other end of the second coil. The control circuit transmits a first current signal to the first coil by the first current pin, and transmits a second current signal to the second coil by the second current pin, the control circuit analyzes the change of the first current signal and the change of the second current signal to determine whether the position of a tag is close to the first coil or close to the second coil.
