Secure communications via NFC device

摘要

A system, method, and apparatus for negotiating a communication link between first and second near field communication (NFC) devices is disclosed. A third NFC device is placed in close proximity with a first host device operatively containing the first NFC device to determine communication information including at least one of a communication mechanism and a data transfer protocol usable by the first host device. The communication information usable by the first host device is stored in a portable device operatively containing the third NFC device. The third NFC device is momentarily placed in close proximity with the second NFC device. The stored communication information of the first host device is transferred from the portable device to a second host device operatively containing the second NFC device. A communication link is established between the first and second host devices to enable the first and second host devices to transfer data between them as a function of the determined communication information.
