 However, critics noted that MyZone represented little more than a redesign of tickets for the existing TravelPass fare collection system, and pointed to the Labor government's failure to implement Tcard, a smart card system abandoned following trials in 2007.Like the previous ticketing range, MyZone used the existing magnetic-stripe automated fare collection system on trains, government buses and ferries.Private bus services and the light rail required manual checking or validation of the ticket by the driver or conductor.
