Abstract: A power receiving system includes a first receiving coil, a second receiving coil, a receiving circuit, a switching circuit, and a shorting circuit. The first receiving coil is at a first location on the cart. The second receiving coil is at a second location different from the first location on the cart. The receiving circuit generates direct current (DC) power from the power received by the first receiving coil or the second receiving coil. The switching circuit connects one of the first and second receiving coils to the receiving circuit. The shorting circuit disables the other one of the first and second receiving coils.

Abstract: An article input device includes a processor. The processor acquires identification information read from a wireless tag by a reading unit installed in a first carrier carrying an article. The processor registers the acquired identification information in a first list when the acquired identification information is not registered in a second list in which identification information read from a wireless tag by a second reading unit installed in a second carrier carrying an article is registered. The processor causes a display on the first carrier to output a notification when the acquired identification information is registered in the second list.
