A near field communication (NFC) system and method for controlling transmission power of the NFC system includes a NFC reader configured to transmit a radio frequency (RF) signal having an initial amount of RF power, a NFC target device in selective communication with the NFC reader, and a NFC transmission power control platform disposed between the NFC reader and the NFC target device. The platform includes a microcontroller and at least one circuit in communication with the microcontroller and configured to determine an actual amount of RF power needed to sustain near field communications between the NFC reader and the NFC target device and configured to regulate the RF signal, where the regulated RF signal contains the actual amount of RF power needed to sustain near field communications between the NFC reader and the NFC target device.
