One example embodiment of a wireless power transmitter described herein includes: a plurality of radio frequency (RF) antennas configured to transmit RF power waves such that they converge to form controlled constructive interference. The example embodiment also includes: a micro-controller configured to: receive from a user device a coded signature signal (and the user device is coupled with a receiver), authenticate the receiver as authorized to receive wireless power from the transmitter according to the coded signature signal, in accordance with determining that the receiver is authorized, obtain from the receiver a set of user-defined restrictions used to determine when wireless power may be transmitted to the receiver; and cause the RF antennas to transmit the RF power waves when the set of user-defined restrictions indicate that wireless power may be transmitted. The example embodiment also includes: a communication component configured to receive from the receiver the coded signature signal.
