biometricsJapanese bank Suruga just launched "Bio Security Deposit," a biometric-based deposit account using palm veins as a user ID. Palm veins are supposed to be a little more user-friendly than iris-scans and are less prone to intereference by dirt than fingerprint scans. The patron needs at least 1 million yen (roughly $10,000) to open the account, and can only withdraw money from that one location. Apparently there has been a growing problem with bankbook theft and identity fraud there in Japan, so hopefully the new accounts won't also lead to an epidemic of theft-induced hand amputations.
