Abstract: A method and a system for transferring a person and the person's carry-on items from a site upstream of a security check point to a site downstream of the security check point comprises loading the person's carry-on items onto a trolley at the upstream site, separating the person from the trolley at the upstream site, and subsequently x-raying the trolley at the security check point while the carry-on items remain loaded onto the trolley, and while a security check of the person is performed. Subsequently, the person and the trolley are united, while the carry-on items remain loaded onto the trolley. The trolley may be made from non-metallic material, such as plastics composite materials, and may optionally comprise a display monitor for displaying user-specific information. The invention is particularly useful for promoting security checks at airports.
