Two plates were put on every vehicle (one on each side), with the stripes distinguishing different information, like the type of equipment and the owners. A scanner was utilized to peruse the plates on the moving cars. In spite of the fact that it proved fairly valuable, the system was abandoned in light of the fact that it was untrustworthy for any long-term use.
