Methodologies, systems, and computer-readable media are provided for reading machine readable features of objects. A local terminal generates a temporary object number corresponding to an unreadable object and captures an image of the unreadable object. A message is sent to a number of portable devices requesting that a duplicate of the unreadable object be located and that a machine readable feature on the duplicate object be read. Once a duplicate object is located, one of the portable devices reads a machine readable feature on the duplicate object, and the portable device calls a service offered by a server to retrieve a data value corresponding to the duplicate item from a database. This data value is then sent to the local terminal invoking a service offered by the terminal to replace the temporary object number with the data value corresponding to the duplicate item.
