An interactive shopping system, or smart cart. The system allows a user to select items in a store and complete a purchase without having to wait in lines or interact with store personnel. The system can have a container for holding products selected by at least one user, a user interface, a scanner in communication with the user interface, a processor in communication with the user interface, and a data storage comprising computer instructions executable by the processor. A user can select products, place them within the container, scan the products, and initiate a payment transaction to complete a purchase.

Disclosed herein relates to a system, comprising: at least one load receiver mounted on a shopping cart or basket and configured to receive an item placed into the shopping cart or basket for a weighing operation; a plurality of sensors configured to detect a plurality of parameters relating to the weighing operation of the item including at least one of: a relative angle between a force sensing axis of the at least one load receiver and a direction of gravity, a motion of the shopping cart or basket, and an ambient temperature surrounding the shopping cart or basket and the at least one load receiver; and a processor configured to determine an actual weight of the item based on at least a portion of the plurality of parameters.

A support roller (30, 30′) for supporting a vehicle on an underlying surface, comprising at least one bearing element which is at least indirectly connectable to at least one supporting structure of the vehicle, at least one fork connected to the bearing element, and at least one wheel (90, 90′) which is mounted in the fork so as to be rotatable about a first rolling axis (R) and can be brought into contact with the underlying surface, at least one sensing device (190 ) for sensing at least one supporting force with which the wheel (90, 90′) is supported on the underlying surface. A vehicle, in particular an industrial truck, comprising at least one support roller and a method for stabilizing a vehicle.

The invention relates to a manually movable and stackable trolley having a supporting device, wherein, when two trolleys are stacked, a rear region which is only taken up by the rear trolley and a front region which is only taken up by the trolley in front are produced, wherein the supporting device is assigned an electronic weighing device which is equipped with a first and a second weighing cell. The two weighing cells are arranged such that, in the stacked state, the first weighing cell of the rear, inserted trolley is within the rear region, and the second weighing cell of the inserted trolley is outside the front region, and, conversely, the first weighing cell of the trolley in front is outside the rear region, and the second weighing cell of the trolley in front is within the front region, wherein the first weighing cell is directed downwards from the at least one supporting device and the second weighing cell is directed upwards.

An information processing apparatus for commodity registration includes a cart body, a weight sensor, a movement sensor, a code scanner, a display, and a control circuit. The control circuit is configured to detect change of a weight according to the weight sensor. Upon detecting the weight change, the control circuit determines whether the code scanner has read a commodity code within a predetermined time period before or after the weight change. If the code scanner has not read a commodity code within the predetermined time period, it is determined whether or not movement of the cart body, as detected by the movement sensor, satisfies a predetermined condition. If the movement satisfies the predetermined condition, the control circuit controls the display to display a registration alert screen.

A food item system may include a remote device associated with a given shopper and a weight sensor associated with a food product display that includes food items. The food item system may also include a food item processing server configured to add at least one user selected food item from among the food items to a virtual shopping cart associated with the given shopper based upon proximity of the remote device to the food product display and a change in weight from the weight sensor indicative that the at least one user selected food item has been removed from the food product display. The food item processing server may also be configured to communicate the virtual shopping cart of the given shopper for checkout.

Provided herein are aspects of a shopping device and system. In one embodiment, a shopping device includes a weight measurement device configured to weigh products placed thereon; a product interface configured to receive product identifiers; and a controller configured to communicate with a remote database and determine that a product identifier received by the product interface corresponds to a first product placed on the weight measurement device, determine a cost of the first product placed on the weight measurement device, and calculate a cumulative weight and cumulative cost of the first product with one or more products placed on the weight measurement device. Embodiments of a shopping system may also include a product carrying device and a user interface, wherein the user interface may include a visual display, an input interface, and a payment interface.

In one embodiment, a log-in control apparatus has a processor which controls an operation for log-in to an information terminal moving along with a carrier for carrying a commodity to be purchased. The processor detects a state in which the commodity is placed on the carrier, in cooperation with a sensor attached to the carrier. The processor detects the operation for log-in to the information terminal, in cooperation with an input device included in the information terminal. When the processor detects the operation for log-in, in a case in which the processor detects the state in which the commodity is placed on the carrier, the processor judges that the operation for log-in is ineffective.
