The New Jersey State Police are planning to install 120 new automated license plate readers around Atlantic City, New Jersey.

San Francisco's police department is set to begin installing 400 automated license plate readers to combat retail theft, among other crimes.

Private firms operating with little oversight are collecting data that some experts say amount to an unacceptable level of surveillance.

While the city is expanding its use of automatic license plate readers, local officials promised to prioritize data privacy.
