New York City is surrounded by bridges and tunnels that practically require you to have an E-ZPass. They have transponders which will read your E-ZPass just for identification purposes. They use that information to report on congestion within the city. According to the maker of the transponder, they keep a hash of the identification number, and throw it away as soon as they have calculated the speed. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
