In one embodiment, first and second near field communication (NFC) equipped communication devices are put into a designated temporary channel and placed into close enough proximity to cause an NFC transaction. The NFC transaction may generate a transaction identifier that may be included in a channel establishment message sent from the first and second communication devices to the communication server. The communication server receives the transaction identifiers from the first and second NFC equipped communication devices and when they match, the communication server creates a temporary communication channel accessible to the first and second NFC equipped communication devices. ## Claims ### Claim 1 A method of managing communication channels in a communication system that includes near field communication (NFC) capable communication devices and a communication server, the method comprising: causing an NFC transaction when a first and a second NFC equipped communication device are placed into close enough proximity of one another, the NFC transaction comprising generating a transaction identifier that is temporarily available to the first and the second NFC equipped communication devices;
