Barclays has teamed up with Japanese technology giant Hitachi to produce a biometric banking authentication device which scans the vein patterns in customers' finger tips, the VeinID.

The technology, a small box with an opening that attaches to the computer via USB, uses infra-red lights that scans the user's fingers and will allow them to access online accounts and make payments without the need for a PIN or password.

The firms said that it is more secure than 'normal' finger scanning technology because the vein patterns and blood flow are very hard to replicate, with a one in a million chance of coming across two people who have very similar patterns.

Barclays said that the biometric reader will be rolled out in 2015.
