Paying Your Fare with Clipper
All Contra Costa transit agencies support fare payment using Clipper. You can load money on either a physical Clipper card or via the
Clipper app on your phone
(no card needed)!
Plus, when you pay with Clipper on County Connection, Tri Delta Transit, WestCAT or Wheels, your fares are automatically capped at a day rate of $3.75, which means all trips and transfers after your second ride of the day are free!
