I feel like it's 10 years too late, though--now I have my smartphone with a TTC tracking app, and I find it much more accurate to see the vehicle's location than an ETA, given my understanding of traffic conditions etc. vs an automated system's. And it takes just a few seconds for me to pull out my phone and see where the next streetcar is...in fact usually I've done it before arriving at the stop. Certainly not a bad thing to have, as I know some people don't have smartphones and we have visitors who might not have an appropriate app/data plan, but for most regular commuters it's a bit of an anachronism.
Apple Pay is supposed to roll out support for that very soon--I would predict an announcement at Apple's developer conference in June where they announce new versions of iOS, followed by a rollout this fall with the new iPhones.
However, I'm much more concerned about
Presto supporting it than Apple...Android has supported this for
years and Presto hasn't given any indication that they plan to support it any time soon. When they don't even have a mobile site or an app to merely check your balance, it seems a bit doubtful that they'll suddenly have NFC support with instant reload...but I certainly hope that they eventually bring that out. And I hadn't even considered the instant reload aspect...that'll put an end to about 99% of the complaints they receive if you go by their twitter account
