A weighing device for the self-service registration of goods in stores contains a floor scale (2), which is disposed in an upwardly open standing container (3). The floor scale (2) has a suspension device (8) for at least one carrying container (11) which is removable from it. It is protected by the standing container (3) against accidental influences from outside, so that prolongations of the weighing procedure are prevented. As a result of the arrangement of the carrying container (11) on the floor balance (3), the departure of the customer with the weighed goods from the weighing area is speeded up. As the weighing receptacle in the standing container (3), a shopping container, for example a shopping cart (21), can also be used. For this purpose, the floor scale (50, 60) is in this case of U-shaped configuration in top view and is provided with bearing elements (52, 71) for the shopping container.
