"BRITONS applying for a new passport will need to undergo fingerprint and iris scans within four years under the national ID card scheme announced yesterday.The so-called "biometrics" which may also include a facial recognition scan could also be extended to driving licences in that time, although a decision has not yet been taken, said British Home Secretary David Blunkett.
It is believed issuing of the controversial new cards will begin in 2007-2008.
The new hi-tech ID will be held by an estimated 80% of the British population by 2013, as people renew their documents, before a decision is taken on whether to force the remainder to get a card. "
