VisaCash security.

I have read that Visa intends to begin a digital cash system, using both discardable and recharable cards that would implement secure cash transations. The system is now in use in Australia, and there are plans for use during the Olympic Games at Atlanta and a pilot project in Thailand. Does anybody know if this is truly "cash"? Is is tracable, and what encryption does it use? ------------------------------------------------------------------------------ Patiwat Panurach Whatever you can do, or dream you can, begin it. eMAIL: pati@ipied.tu.ac.th Boldness has genius, power and magic in it. m/18 junior Fac of Economics -Johann W.Von Goethe
