Abstract
A considerable memory stores data on individual automobiles, addressed by alphanumeric-code license designations. Access to the memory also is provided from individual telephone terminals through an interface structure with digital and audio capability in association with a code translation unit which enables use of telephone keypad compatible codes to address the memory. The translation involves the addition of a check digit. A caller accessing data on a specific automobile may renew the license and in that regard infractions are policed. Also, billing is performed through a credit system with verification.
