INSPASS, or INS Passenger Accelerated Service System, was a program of the United States Immigration and Naturalization Service (INS) during the late 1990s and early 2000s the purpose of which was to facilitate the entry of pre-screened low-risk travellers through immigration and customs at certain airports. Upon entering the United States after arriving from abroad, users would subject themselves to hand geometry scans and would pass through Federal Inspection without undergoing a formal interview by border personnel.
