A person desiring to check out articles protected by security tags deposits these articles at one end of a check-out aisle. From there, they are transported to the opposite end of the check-out aisle as part of the check-out procedure. The person who deposited the articles is restrained from accompanying these articles all the way through the check-out aisle, but is able to reach its opposite end only via a path which is separate from the check-out aisle itself. That separate path is equipped with an electronic article surveillance system. The same separate path and its associated electronic article surveillance system serve several check-out aisles.
