The system, which Cubic delivered and operates, will enhance travel options for commuters in parts of the East and North Bay.

The agencies joining Clipper later this year include the Marin Transit, Napa VINE, SolTrans, Fairfield and Suisun Transit, Rio Vista Delta Breeze and Vacaville City Coach bus systems, as well as San Francisco Bay Ferry’s Vallejo-San Francisco route.

By the end of 2015, it will extend to the Livermore-Amador Valley Transit Authority bus network and County Connection, Western Contra Costa Transit Authority and Eastern Contra Costa Transit Authority bus systems, with Santa Rosa CityBus, Sonoma County Transit, Cloverdale Transit, Petaluma Transit and Healdsburg Transit systems set to be integrated by spring of 2016.

The reloadable Clipper smart card currently allows the Bay Area Rapid Transit, San Francisco Municipal Transportation Agency, Alameda-Contra Costa Transit, Golden Gate Transit & Ferry, San Francisco Bay Ferry, SamTrans, Caltrain and the Santa Clara Valley Transportation Authority riders to transfer from one agency to another by simply touching the card to the reader on buses and light-rail vehicles, or at rail stations or ferry terminals — using one card to pay for all rides.

Under the updated contract, Cubic will install and configure Clipper fare collection equipment on all East Bay and North Bay operators’ buses, install retail devices and handheld card readers for fare inspection, and install wireless networks to support the uploading and downloading of Clipper data at all bus garages.
