Exemplary embodiments are directed to communicating information relating to wireless charging. A power transmitting system includes a host device with a transmit antenna. A communication interface conveys receiver information, which includes unique identifier information, from a receiver device to the host device. A controller on the host device monitors and processes the receiver information to generate notification information, which is presented to a user on a user-perceivable notifier. The transmit antenna generates an electromagnetic field at a resonant frequency to create a coupling-mode region within a near-field of the transmit antenna. The system can detect a presence of a receiver device with a receive antenna that is in the coupling-mode region and process a request for power from the receiver device. The system can also notify a user when a host device is leaving a designated region and whether the host device includes expected receiver devices.
