Fujitsu has launched a Â“Palm VeinÂ” scanner which can identify people without any direct contact.
The company speculates that the scanner could be used by bank customers to withdraw funds from cash points with a single hand gesture.

Data about your hand layout can be stored on a computer or on a bank card.
