<p>The present invention provides for automation of the process of ensuring that the contents of the return mailed digital media (123), comprising a disc (100) enclosed in a sleeve (110), is correct for redistribution. A camera (125) on a sorting machine is used to scan a first code (102) on a hub (101) of the disc (100) through a sleeve opening. The camera (125) also scans a second code printed on the sleeve. The sorter computer (132) compares the first and second codes to determine whether the first and second codes correspond. If the first and second codes do not correspond, the sorter (127) outsorts the mailed digital media so that the mismatch problem can be corrected. In a further embodiment, the system detects whether there are more or less than a single disc (100) in the mail package (123). In the preferred embodiment, the mailed digital media (123) is further composed of an envelope (110) that receives and encloses the sleeve. The sorter scanner (125) arranged for scanning the first code is also arranged for scanning the second code through an envelope opening, preferably the same envelope opening used for scanning of the first code.</p> |
