TORONTO, ON - OCTOBER 5 - A Presto reader is seen on the 7 Bathurst bus on October 5, 2016.
An audit conducted of Presto readers on TTC buses found that 12 per cent of the devices weren't working, and five per cent of buses had no working readers at all. This raises questions about the fare card system that is supposed to replace all other fare media by the end of next year. Carlos Osorio/Toronto Star
