Tracy Lehr / KEYT GOLETA, Calif.--Riders hopping on the Clean Air Express or Santa Barbara Metropolitan Transit District buses don't have to have cash on hand anymore. Contactless payment options are being introduced in the tri-county region on Santa Barbara County public transit systems. Clean Air Express customers will also pay a dollar less as those contactless payments will be $6 rather than the standard $7 one-way cash fare. Multi-ride fare discounts are also being honored. It's part of a pilot program in Santa Barbara, San Luis Obispo and Ventura Counties. It is also happening in a fe other regions including Monterey, Salinas and Sacramento.
