Using Clipper on Marin Transit
You can use cash value on your Clipper card on all Marin Transit routes except the Muir Woods Shuttle (Route 66/66F). Adult riders will always get a 10 percent discount over paying with regular cash. Clipper 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 your Clipper card, locate a card reader on the bus. 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 will deduct the maximum 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 your next trip. 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! You must "tag off" when you exit the bus to ensure you are charged the correct fare. Clipper deducts the maximum fare from your starting zone and then refunds the difference when you tag your card to the card reader upon exiting.
Clipper automatically calculates the transfer period and transfer discounts, so you do not need a paper transfer.
