Fingerprinting of all visitors to US upon entry and exit

From the Washington Post:
"The U.S. government today will order commercial airlines and cruise lines to prepare to collect digital fingerprints of all foreigners before they depart the country under a security initiative that the industry has condemned as costly and burdensome."
. . .
"Launched after the Sept. 11, 2001, terrorist attacks, US-VISIT is intended to automate the processing of visitors entering and exiting the country, using fingerprints and digital photographs to help find criminals, potential terrorists and people who overstay visas and join the nation's illegal immigrant population."
