What will SEPTA Key 2.0 look like? The mass transit provider is seeking proposals from experienced vendors to "develop, implement, and maintain" upgrades to its fare payment system.

Under SEPTA's Key Advantage program, small businesses now can purchase discounted monthly transit passes to be given to employees for free. The program began as a test last spring.

From tokens to key cards, now to your cell phone. The transit agency wants to expand its mobile ticketing program, which it tested over the summer.
