摘要:
To promote ease of use, as well as a reduction in bit error rates during extended data exchange between a coupled NFC tag/reader pair, signal strength is measured from a plurality of NFC tag antennas each positioned differently with respect to a common reader field, and differences in signal strength are used to determine an optimum positioning of the tag, or tag emulator, with respect to the reader. Alternative embodiments may include signal time of flight for determining orientation of the NFC antennas within the reader field. Information is generated by the tag, or tag emulator, and output by the tag, or tag emulator, such that a user may direct the positioning of the tag, or tag emulator, for improved communication with the reader.
