Abstract: A lockable container (1) for receiving items includes elements for generating a random code when the container is locked, elements for transferring the code to a person locking the container, and a memory for storing the code. The container further includes elements (2) for unlocking the container to a first stage, in which the contents of the container can be viewed by a user but not removed from the container, and elements for transferring the code to the user when the container is unlocked at the first stage. The container can then be unlocked to a second stage (3), in which the user can remove the contents of the container and the code is removed from the memory.
