Abstract: A system for delivery or collection of goods from a customer's home comprises a central control system which monitors and controls a plurality of enclosures, each enclosure (1) being protected by releasable locking means or deactivatable alarm means associated with data communication means, e.g. a mobile telephone type unit (4,5,6). The central control system, e.g. a computer (40), generates a new security code for each delivery which is transmitted to the data communication means, and which when subsequently entered into security code input means, e.g. a keypad (6) or an RF tag reader, associated with and accessible from outside the enclosure, affords access to the enclosure enabling a person to deliver or collect an item (50). The central control system may be provided by a delivery service (51,52) and may communicate automatically with the box owner via telephone (20) or mail (PC 30).
