Automated license plate readers have become widespread, with nearly 150,000 operating across the United States. Most of these readers are manufactured by Flock Safety. The network captures a large volume of vehicle reads, with 20 billion recorded each month.

This technology has its roots in the United Kingdom, where it was developed following a deadly bombing campaign in 1974. The UK's initiative, known as "Project Laser," led to a nationwide database that aided in thousands of prosecutions.

Further details on the history and expansion of license plate readers are available, including their adoption by US Customs and Border Protection in 1998.
