The DHS November 14 Industry Day forum will feature the government asking contractors to offer solutions for Customs and Border Patrol agents.
The technology envisioned would seamlessly track the faces of foreigners without requiring them to decelerate or take off their glasses or hats.
The Government Accountability Office, Congress' watchdog agency, reported in May that DHS "lacked a comprehensive biometric exit system at US ports of departure to capture information on nonimmigrant visitors who exit the United States."
"Without a complete exit system, DHS relied on third-party departure data such as commercial carrier passenger manifests, to confirm a visitor's departure from the country. However, these commercial sources occasionally provided false departure or arrival status on visitors," GAO said.
The government expects to pay between $50,000 to $200,000 for the tech. The government will also buy a corresponding technology that anonymizes the data of people crossing the border who are US citizens so that the program only surveils foreign nationals.
