In 1993, the

If a transponder is not detected, cameras photograph the vehicle’s license plate and attempt to match it to a FasTrak account. If no account is found, either an invoice with no penalty (in locations supporting "pay by plate") or a violation notice is issued and mailed to the registered owner of the vehicle.
Tag types

FasTrak supports multiple transponder types:
* Standard tag – A hard-case transponder used on all FasTrak toll roads.
* Sticker tag – A low-cost adhesive tag issued by some agencies.
* FasTrak Flex – A switchable tag (settings for 1, 2, or 3+ occupants) required for HOV toll discounts.
* FasTrak CAV – Identifies Clean Air Vehicles (CAVs) for applicable toll discounts.
Some toll roads allow carpoolers to avoid tolls by placing their standard tag in a mylar bag to block the radio signals, others require a FasTrak Flex transponder.
Service center operations
All Bay Area toll facilities use a centralized billing and customer service system operated by the
Bay Area Toll Authority (BATA).
Transportation Corridor Agencies, operator of the Orange County toll roads, also operates the billing and customer service system for the San Bernardino County high-occupancy toll lanes.
Although the
91 Express Lanes is operated by both the
Orange County Transportation Authority and the
Riverside County Transportation Commission, that facility uses a centralized billing and customer service system operated by the former.
All other Southern California agencies maintain separate billing and customer service systems.
Some agencies "sell" (charge the initial prepaid toll deposit) transponders in a retail setting, such as

FasTrak account fees and requirements vary by issuing agency:
Security

In 2008, researchers found that FasTrak transponders lacked encryption and could be queried or updated remotely.
As the Title 21 specification is publicly available, this raised concerns about potential misuse.
Transponders are also used to generate

History
After the first electronic toll collection (ETC) system in North America was implemented on the
Dallas North Tollway in 1989, various toll agencies in California began expressing interest in similar systems. Given that toll roads and bridges in the state are managed by different government entities, there was concern about the potential emergence of multiple, incompatible ETC systems. To address this, the
California State Legislature
The California State Legislature is the bicameral state legislature of the U.S. state of California, consisting of the California State Assembly (lower house with 80 members) and the California State Senate (upper house with 40 members). ...
passed Senate Bill 1523 in 1990, directing the
California Department of Transportation (Caltrans) to create a standardized statewide technical specification for ETC systems.
California subsequently became the first U.S. state to require all toll facilities to use a uniform ETC system. This specification was later codified in Title 21, Division 2, Chapter 16 of the ''

became the first toll facility in California to implement ETC when it opened in 1993. The
Transportation Corridor Agencies (TCA), which manages the toll road, branded the system as "FasTrak". TCA still holds the trademark for the "FasTrak" name and logo.

The original FasTrak transponder was a device about the size of a

was inserted. However, the device was costly to produce and the smart card offered little advantage to customers. By 1995, when the
91 Express Lanes opened, the transponders had been redesigned to be coaster-sized.
FasTrak was subsequently deployed on the

Adapting FasTrak for California’s toll bridges required additional modifications, especially to handle 18 different toll classifications for trucks. After a trial at the
Carquinez Bridge in 1996 revealed accuracy issues, improvements were made, before the bridge adopted FasTrak in 1997. Despite these developments, other state-run Bay Area toll bridges did not adopt the system until October 2000, due to bureaucratic and technical delays. The independently managed

The
San Diego-Coronado Bridge briefly used FasTrak before tolls were eliminated in 2002. In 2005, the Bay Area FasTrak Customer Center opened, consolidating services for regional bridges and the Golden Gate Bridge.
FasTrak has since expanded to cover all new toll facilities in California, which are required by law to adopt the system. In 2009,

The introduction of the
Metro ExpressLanes in Los Angeles in 2012 led to the introduction of FasTrak Flex transponders with occupancy switches (1, 2, or 3+ riders), allowing automated toll calculations for carpools and solo drivers.
TCA began issuing switchable transponders in 2013, followed by the
91 Express Lanes and the Bay Area in 2015.
The TCA introduced a sticker transponder in 2019 to replace the earlier plastic model. The new sticker transponders cost the agency less than $1 each, compared to approximately $20 for the plastic version. The lower cost enabled TCA to eliminate monthly account maintenance fees and the requirement for a prepaid deposit.
California continues moving toward

The Golden Gate Bridge became fully cashless in March 2013, followed by TCA-operated toll roads in May 2014. In 2019, California approved the phaseout of toll takers on all state-owned bridges.

Toll facilities using FasTrak
Current
All eight toll bridges only collect tolls in one direction. All other toll facilities collect tolls in either direction, though some high-occupancy toll lane toll lanes exist in only one direction of their freeway in parts or the whole of their length.
''^'' indicates that carpools require the switchable "FasTrak Flex" transponder.
''HOV 2+'' indicates that carpools require two or more persons.
''HOV 3+'' indicates that carpools require three or more persons.
''†'' indicates that two-person carpools are tolled differently than solo drivers or carpools with three or more, typically at a rate intermediate between the solo and 3+ rates
