Abstract: A parcel delivery locker has a body portion formed by four panels that are joined to each other along hinge joints at their vertical edges. The hinges joints allow the body portion to be alternatively configured into a stack for shipping, or as a box for use in receiving and containing parcels. A lid is joined to the body portion during assembly and has an electronically controlled locking mechanism that can be wirelessly controlled to lock or unlock. A floor portion is coupled to the four panels as well.

Abstract: A reduced size optical code identifier includes a transparent body having a flat bottom surface with a rounded or domed top surface that meets the bottom surface around the perimeter of the bottom surface. An optical code is provided in the body adjacent the bottom surface and is visible through the top surface. The top surface is configured to reduce reflection to facilitate optical recognition and decoding of the optical code. The body has a maximum length or diameter of about twelve millimeters or less. The identifier can be placed on an object or structure and then used to associate information with the optical code of the identifier so that the information can be retrieved using a computing device that can optically recognize the code and communicate with a remote server.
