US Customs and Border Protection and San Diego International Airport have jointly unveiled eight automated kiosks in the airport's customs inspection area.
These self-service kiosks will help passengers to submit their customs declaration and personal information electronically.
Officials estimate that the new systems will reduce processing times by 25% to 40% and, in some cases, by up to 50%.
Port of San Diego CBP director Bill Snyder said: "This technology will help our officers efficiently process an ever-growing volume of international travellers.
"The kiosks are designed to reduce wait times and congestion in the federal inspection services area while maintaining the highest standards of security."
Different from the global entry kiosks installed in 2012, passengers will not require pre-registration or membership to use the system.
Travellers will be able to scan their passport on those kiosks, take photos and answer customs declaration questions on a touch screen. The receipt obtained from the kiosks needs to be shown to a CBP officer when a passenger exits the inspection area.
San Diego County Regional Airport Authority president and CEO Thella Bowens said: "San Diego International Airport welcomes nearly 30,000 arriving international passengers each month.
"Now, for many of those passengers, getting through customs will be much easier and quicker."
Along with San Diego, a total of 30 other airports are installing the kiosks that will offer service for people holding US or Canadian passports, or belonging to the Visa Waver programme.
