Abstract: A self-checkout system for controlling an exit of a checkout area (110) is provided. The system comprises a sensor arrangement (120) comprising at least one sensor (140), wherein the sensor arrangement (120) is configured to track, by the at least one sensor (140), a person being inside the checkout area (110), receive a payment signal confirming a successful payment by a person (1), receive an exit detection signal, from the at least one sensor (140) representing that a person (1) is at a predetermined distance from the exit in the checkout area (110), and determine if the exit detection signal and the payment signal correspond to the same person (1), and if so transmit an opening signal to said exit so that said person (1) is allowed to exit the area (110).

Abstract: The invention relates to a folding door with a door leaf (4) which is movable between a closed position and an open, folded position, in which the door leaf (4) is folded about folding lines between opposite side edges (5) of the door leaf. A plurality of guide members (110-118) are connected to the side edges (5) in a spaced-apart relationship along the same, and two side frames (1) are extended adjacent to a respective side edge (5). Each side frame (1) defines at least a first and a second guide groove (68, 69), which are juxtaposed transversely of the side frame. The guide members comprise, at each side frame (1), a first set of guide members running in the first guide groove (68) only, as well as a second set of guide members running in the second guide groove only (69).
