Using Clipper on AC Transit
You can use Clipper on all AC Transit buses.
Clipper automatically figures out the cost of your ride, including all discounts and transfers. See Fares and passes for more information on the types of value available.
To use Clipper on AC Transit, locate the Clipper card reader on the bus, either attached to the pole on your left as you board or near the fare box. Tag your card by holding it flat against the Clipper logo on the reader, and wait for the beep and green light. The card reader either will verify that you have a valid pass and display the expiration date or will deduct the cash value fare and show your remaining balance.
If your card balance is low, the reader will beep twice and display a yellow light. You can still board the bus, but you will need to add value to your card before you pay your next fare. If you do not have enough value on your card, the reader will beep three times and display a red light, and you will not be able to pay your fare with Clipper.
Important! If you are traveling locally on a transbay bus, let the bus operator know before you tag your card so that the card reader can be switched to the local fare, ensuring you're charged correctly.
