Presto has more problems at Toronto subway stations

Are you among the six per cent of TTC riders who use Presto to pay your subway fare? If so, you might have had a little trouble adding money to your card using the self-reload machines.

The Toronto Star reports that Metrolinx is investigating the self-reload machines at TTC subway stations because they haven't been meeting the transit organization's performance or reliability targets.

Metrolinx isn't sure why the machines aren't working properly, but the problems started emerging within the past two to three weeks. As the Star notes, one person couldn't find a single working machine at Union Station last week.

Presto still has lots of kinks to iron out before it replaces most other payment methods on the TTC some time next year.
