Commuter rail customers on all North Station lines will be able to purchase and display tickets on their smartphones starting Monday, with South Station lines and ferries expected to follow after Thanksgiving.
The launch follows a successful test among some South Shore customers and comes half a year after the T signed an agreement with a British mobile-ticketing developer to make it the first major US commuter rail to offer passengers an alternative to paper.

First impressions: I couldn't find a Senior discount rate option (important as I'm 65) in the ticket prices. And the app needs an alpha search feature for finding stations faster. Scrolling to find a station is old fashioned. Put the alphabet down the right side as in other programs to link to a station letter. Maybe I missed these features in my first look. Hey, I told you I was 65, didn't I? Otherwise, I applaud the T for this move. Now if we could get the trains to run on time we'd might have something. Peter Newburyport
Still can't get an answer as to how the monthly pass purchase will cover subway rides
