Grad students forced to have palm scans before writing tests

In a move that has prompted at least three complaints to Canada's privacy czar, a growing number of professional programs such as medicine and business now require students to give a digital print of their finger, thumb or even veins in their palm to write the high-stakes entrance tests designed and run out of the United States.
The latest version is the new infrared scan of the blood vessels in your palm required by all 266,000 students around the world – 8,000 in Canada – who write the four-hour GMAT admissions test each year for a master's of business administration (MBA) program.
