Devices, systems and methods are disclosed for additional security, functionality, and convenience in the operation of a wireless communication device with the use of a separate proximity security token in communication with the wireless communication device. In exemplary embodiments, the token is carried by the user while device logic is installed on the user's wireless communication device. The device logic along with transceivers allows the device to sense proximity of the token through wireless communication. Given a certain range of the proximity security token, as determined by the wireless signal strength, the device logic determines whether the device is in a locked or unlocked state. If the proximity security token is outside the range, then the device is locked. The proximity security token uses ultra low power communications for optimal battery life.
