The device works by matching the vein pattern of a person seeking access, for example, to an automated teller machine (ATM), with scanned biological information stored in its database.
To get into the database, your palm is scanned without touching the device.
Fingerprints are the features most commonly used in biometric security systems; you're given access if your print matches the copy stored in the system.
The trouble is, such scanners are expensive to set up and manage—and there is little evidence that they provide better security than less costly passwords.
Fujitsu's goal is to enhance reliability by using blood vessels in the palm rather than fingerprints.
