"Fujitsu's palm vein authentication technology consists of a small palm vein scanner that's easy and natural to use, fast and highly accurate. Simply hold your palm a few centimeters over the scanner and within a second it reads your unique vein pattern. A vein picture is taken and your pattern is registered. Now no one else can log in under your profile. ATM transactions are just one of the many applications of this new technology. "
