ABSTRACT:
A near field communication (NFC) device is capable of operating as an NFC initiator device or an NFC target device for exchanging request and response messages with another similar device in order to determine a secondary transport mechanism suitable for communications between the two devices with bandwidth greater than available for NFC and for determining appropriate roles for both devices without excessive communication. Such determination of roles can be determined by rule or by exchanging information indicating a choice of roles.
