Privacy Impact Assessment for the Automated Passport Control (APC) and Mobile Passport Control (MPC) [open pdf - 567KB]
"The U.S. Department of Homeland Security (DHS) U.S. Customs and Border Protection (CBP) developed the Automated Passport Control (APC) and Mobile Passport Control (MPC) programs to automate and expedite eligible travelers' entry process into the United States. These programs enable travelers to perform select entry declaration and inspection requirements tasks through a self-service kiosk (APC) or a mobile device application (MPC). DHS is conducting this Privacy Impact Assessment because APC and MPC collect personally identifiable information (PII) from members of the public."
