A system includes a dispenser and a transmitter. The dispenser is configured to support and dispense product. The dispenser includes: a housing; an antenna disposed and configured to receive electromagnetic energy that originates from the transmitter; a power supply disposed within the housing and configured to convert the electromagnetic energy received at the antenna into DC (direct current) power; a dispenser mechanism configured and disposed to dispense the product from the dispenser on command; a controller disposed in operable communication with the power supply and the dispenser mechanism; and, an actuator disposed in operable communication with the controller. Upon actuation of the actuator, and upon presence of the DC power, the controller is responsive to facilitate action by the dispenser mechanism to dispense the product. The transmitter is configured to transmit electromagnetic energy and is disposed in operable communication with the dispenser.
