Near field communication system and method for controlling transmission power of near field communication system

A method for controlling transmission power of a near field communication system including a near field communication (NFC) reader, a NFC target device, and a separate NFC transmission power control platform disposed between the NFC reader and the NFC target device including a microcontroller and at least one circuit in communication with the microcontroller, the method comprising the steps of:

• transmitting a radio frequency (RF) signal having an initial amount of RF power from the NFC reader;
• receiving the RF signal by the NFC target device;
• determining an actual amount of RF power needed to sustain near field communications bi-directionally between the NFC reader and the NFC target device with the at least one circuit;
• and
• dynamically regulating a strength of the RF signal with the at least one circuit so that the regulated RF signal contains the actual amount of RF power needed to sustain the near field communications bi-directionally between the NFC reader and the NFC target device.
