Claim 12:
13. A sales device for self-checkout of goods in a store, the store comprising at least one shelf with automatic removal monitoring and with a proximity sensor, and a network for exchanging data, the at least one shelf with automatic removal monitoring for detecting removed items is configured to perform the following:
receive a signal from at least two weighing cells arranged in corners of a rigid body forming a display area with at least two product areas, the signals corresponding to weight forces in an area of the corners of the rigid body; determine coordinates of a center of gravity and a total weight force from the received signals; receive a signal corresponding to a new weight force of at least one of the weighing cells, and determine coordinates of the new center of gravity from the data currently received by the weighing cells; determine a product area, of the product areas, and a weight of the items removed from the determined product area;
determine the item data of the item removed from the shelf on the basis of the determined product area, and determine the number of items removed on the basis of the weight removed from the product area and a specific weight of the item, the sales device comprising:
a controller for controlling the sales device;
a communication unit configured to receive the data from the network; and
a database configured to store item data and object-describing attributes associated with the items,
wherein the controller is configured to receive, via the network, from the at least one shelf with automatic removal monitoring, the item data of the removed items and a customer identification number associated with the item data and read out by the proximity sensor,
wherein the controller is configured to determine, from the item data, the customer identification number, and the read out of the proximity sensor, a list of the items intended for payment, and
wherein the sales device comprises a detector having at least one sensor and an evaluator, wherein the detector is configured to use the evaluator to determine, on the basis of the data of the sensor and the list of the items intended for payment, for which items a payment transaction is to be executed.
