Business Schools Try Palm Scans To Finger Cheats

John Hechinger:

In a sign of increasing concern about cheating, the nation’s top business schools will soon require a high-tech identity check for standardized admissions tests.
Aspiring corporate executives taking the Graduate Management Admission Test, or GMAT, will have to undergo a “palm vein” scan, which takes an infrared picture of the blood coursing through their hands. The image — which resembles a highway interchange in a major city — is unique to every individual. The scans are used widely in Japan among users of automated teller machines but only recently have appeared in the U.S.
Palm-vein scanning on GMAT test takers will begin next month in Korea and India, with U.S. centers starting as early as this fall and a world-wide rollout by May.
