Abstract
A checkstand system including a counter surface within which a plurality of induction charge transmission coils are embedded in or disposed below the counter at selected charge positions about the countertop whereby a cordless peripheral, such as a data reader, is positionable and movable between multiple positions about the counter surface, the peripheral including an induction charge receiving coil operative to receive a charge current from one of the induction charge transmission coils when the peripheral is placed in proximity of a selected one of the charge positions on the checkstand. In one configuration, the system includes a temperature sensing component disposed proximal to an induction charge transmission coil and a controller operative for receiving a temperature signal from the temperature sensing component and adjusting the charge current delivered to the induction charge transmission coil in response to the signal.
