Overall, I used it to pay and it was pretty seamless, and faster than swiping a physical card. I didn't use the app to hail a cab. (Again, stick arm up

I believe that, if you use Way2Ride to hail the cab, the driver has to indicate that they've picked up the hailing passenger, and that the ride has started, rather than just turning on the meter.
