johnslater writes: The Chicago Transit Authority's new "Ventra" stored-value fare card system has another big problem. It had a difficult birth, with troubles earlier this fall when legitimate cards failed to allow passage, or sometimes double-billed the holders. Last week a server failure disabled a large portion of the system at rush hour. Now it is reported that some federal government employee ID cards allow free rides on the system. The system is being implemented by Cubic Transportation Systems for the bargain price of $454 million.
