Abstract
A charging pad capable of charging a receiver according to a predetermined procedure is disclosed. The charging pad may have a plurality of charging coils and a controller for selecting an appropriate coil for charging the receiver. The receiver communicates with the charging pad via NFC, thereby indicating to the charging pad the appropriate procedure for charging the receiver. The controller then selects the appropriate coil and directs charging according to the appropriate procedure.
