Abstract: An example shopping cart is described. The example shopping cart includes a frame, a basket portion mounted to the frame, two or more wheels mounted to the frame for transporting the shopping cart within a geographic area, and an assistance unit mounted to the frame. The assistance unit includes a radio-frequency identification tag configured to transmit a signal for receipt by a radio-frequency identification reader. The assistance unit includes an actuator configured to be selectively actuated between a first position that prevents the radio-frequency identification tag from transmitting the signal from the assistance unit and a second position that facilitates transmissions of the signal from the assistance unit.
