As BART or Bay Area Rapid Transit transitions into clipper card only, they are eliminating paper waste and providing a more economical approach to travel. When speaking with an agent passing out the cards he provided a pamphlet and link to access your online account. This sounds like a great idea, although a more useful platform would be a mobile app. In this way we can eliminate the greater use of clipper cards and the kiosks to reload the cards. All transactions would have the chance to be handled completely on the app for security and less waste.
