Abstract: A method operates a sales device for goods. The method includes: detecting, using a shelf with automatic removal monitoring, a removed item and determining item data of the removed item; reading out a customer identification number of a customer in a vicinity of the shelf from which the removed item has been removed; receiving, by a controller, the item data of the removed item and the customer identification number; adding, with the controller, the item data of the removed item and the customer identification number to a list of items intended for payment; and detecting, with a detector, items for which a payment transaction is to be executed. The detector has at least one sensor and an evaluator and for detecting articles, at least the data of the sensor and the list of items intended for payment are being made available to the evaluator as input variables.

The method includes: detecting, using a shelf with automatic removal monitoring, a removed item and determining item data of the removed item; receiving the item data of the removed item; adding the item data of the removed item to a list of items intended for payment; receiving an item number from a product scanner; adding the item associated with the item number to a list associated with the product scanner; identifying the product scanner at the sales device; collecting, with at least one sensor, data about items in a shopping cart or a shopping basket which is located on a support plate of the sales device; and validating the list of items associated with the product scanner on the basis of the data from the at least one sensor and the list of items intended for payment.

Abstract: A method of operating a device for indicating an event notification to a user comprises indicating a new event through accordingly controlling visual, audible and/or tactile indicators. A user input is received in response to the indicated event. In case a user input in response to the indicated event is not received within a first time period, sensors in the device are controlled to monitor ambient conditions and determine corresponding pattern. In case of a change in the pattern of the ambient conditions by a predetermined amount within a second time period, the new event is indicated once more to the user.
