Abstract
Embodiments provide for a method of allowing for communication between a portable device comprising a portable device NFC antenna and a user device comprising a user device NFC antenna using a bridge apparatus comprising a large coil, a small coil, and an amplifier circuit electrically coupling the large coil and the small coil. The method includes the small coil in the bridge apparatus receiving a near field communication (NFC) signal from the user device NFC antenna. The amplifying circuit can amplify the NFC signal to obtain an amplified NFC signal. The large coil in the bridge apparatus can transmit, to the portable device NFC antenna, the amplified NFC signal.
