Long-promised tap-to-pay system for T finally approaching rollout

Stacy Thompson of the advocacy group Livable Streets and Chris Dempsey of the urban design firm Speck Dempsey join Radio Boston to discuss the MBTA's announcement that it will launch a long-delayed tap-to-pay fare system this summer.

Correction: A guest on Radio Boston incorrectly said the MBTA planned to automatically upgrade passes for riders based on how often they swipe in an effort to cap fees. T officials clarified to say that the proposal, which was listed in a presentation the T released about the new system, is still under review and the T "has not committed to fare capping."
