Bay Area public transit
The nine counties of the San Francisco (California) Bay Area are connected by a network of local and regional transit systems. All systems listed in this guide, even those that are shuttles, are open to the general public. Each transit agency has its own web site and telephone lines, but schedules and interactive trip-planning information for all the systems are also available at 511.org, or, except as noted below, by calling 511 from a phone within the Bay Area. 511.org covers not only public transit, but also other transportation modes, such as driving, bicycling, and ridesharing.

Clipper card
The Clipper card is a smart card for pre-paying transit fares. Benefits of using the card can include the convenience of not having to put money into fare boxes for individual rides, and cost savings when making multiple trips.
As of January 2016, the use of Clipper to pay for parking is being tested in 5 San Francisco garages.
Should I buy a Clipper card?
You do not need a card to use public transit in the Bay Area, since you can always deposit money into a fare box or ticket machine. The card costs $3, plus the money you pre-pay for rides, so it probably doesn't make sense if you plan to take only a few rides on public transit. On the other hand, some agencies (e.g., BART, CalTrain) charge less for tickets purchased with Clipper. Savings can be even greater when you take several rides on the same day. For instance, the Santa Clara Valley Transportation Agency (VTA) no longer issues transfers or day passes, but the maximum daily amount that is charged to the card of an adult (age 19–64) for non-Express rides on the system is $6, the cost of 3 individual adult rides. (For seniors, the maximum is equivalent to 2.5 senior rides.) An additional factor to weigh is the convenience of not having to deposit exact change into fare boxes, versus the inconvenience of buying and recharging the card.
Buying and reloading the card
Clipper cards for adults can be purchased for $3 at most Bay Area Walgreens and Whole Food stores and other retail locations. Youths (age 5 to 17 or 18, depending on the transit agency), seniors (65 or older), and the disabled are eligible for special cards that are good for discounted rides. You can get these from a Regional Transit Connection center (typically, the offices of the local transit agency) or by mail (allow 10 days for delivery). For details, go to www.clippercard.com/ClipperWeb/discounts/index.do or call one of the customer service numbers listed in section For more information, below. Allow 10 days for delivery.
Once you have the card, you can add money to it at any of the retail locations, or online. The first time you add money online, there will be a delay of a few days before you can use it.
Using the card
Clipper card readers are located on buses and at train stops. Hold the card next to the reader. It is not usually necessary to remove the card from your wallet. The reader display will indicate whether the payment was successful, and how much money is left on the card.
Transfers
Sometimes when you transfer from one public-transit vehicle to another (e.g., from BART to a bus) the fare for the second ride is discounted. Procedures vary by transit agency. In some cases, the discount is applied automatically (if you used the card for both rides). In others, you can save money by requesting a paper transfer. Ask the vehicle operator or station agent which procedure applies.
