Abstract

A system for controlling the operation of a remote device via wireless communication. The remote device includes resources for communication via at least two different short-range wireless mediums with different operational ranges. The sensing of a scanning communication signal from a first wireless medium may trigger the disconnection of the remote device from an already established connection, through a second wireless communication medium, to the scanning device. The remote device may provide a remote device ID to the scanning device. As a result of this transaction, one or both devices may experience a mode change, which may be signaled by a audible, visual or tactile confirmation to a user.
