Title: Synchronized indicator light for secure connections

Abstract: A secure communication channel between first and second radio frequency communication devices is indicated by the synchronized indicators on each of the two devices. The indicator may be a light or speaker. After a secure channel is established, the indicators may be simultaneously operated so that a user may definitively and positively determine that the two devices are securely connected to each other. Any interloper devices would not be indicating on the same pattern and thereby be identified.
