Abstract: Described herein are architectures, platforms and methods for dynamic amplification/boosting of near field communications (NFC) antenna transmission power in a device during NFC related functions that require increase in an NFC antenna transmission power such as a payment transaction. For example, to comply with Europay MasterCard and Visa (EMVco) standards with regard to higher NFC antenna transmission power during the EMVco transactions, the NFC antenna transmission power may be dynamically controlled to maximize efficiency of a battery/power supply of the device.
