Abstract
A near field communication (NFC) system includes an NFC reader that communicates with a remote NFC device through load modulation. The NFC reader transmits a wireless carrier signal from an antenna and has a plurality of passive receive antennas to receive the modulated signal. The NFC reader also has circuitry to provide a plurality of data streams that define data recovered from the modulated wireless carrier signal received from the plurality of receivers. The circuitry then selects, based on a location of the NFC device relative to the NFC reader, one of the plurality of data streams for use in processing a transaction.
