A method of securely transferring user data from a first communication device to a second communication device includes receiving with the first device a public encryption key transmitted by the second device over a first communication medium using a first communication protocol. The adjustment in the azimuth pattern is accomplished by means of moving the electrically floating reflector device in an arc around a line parallel to the axis of the antenna. A determination of a second local device having the data is made. The system may further include a spring-urged pusher movably mounted on the base. The installing portion includes a manipulating section.
