I'm just applying to have my Passport renewed and UK Passports are currently been produced, during a phasing in period, in the old and new format (ie Digital and Biometric) . So it's pot luck - you may get a future proof Biometric type or an old Digital type. The new Biometric Passport will have an additional transparent page with the chip inserted in that. The picture you submit will also have to meet very tight criteria as the Biometrics works by measuring facial features - so don't smile, in fact look miserable!

The USA will only accept Biometric Passports from October 2006 (but I believe they may have added a 1 year extension to this to allow others time to comply).

Welcome to our forum.

Biometrics is already with us in many ways. I use a Biometric-enabled keyboard, and I have fingerprint recognition installed on all my office machines and my laptops.

Several UK banks are currently trialing biometric security measures for ATM machines, and when I visit America my face is biometrically scanned on entry.

I'm not being funny when I ask this, but presumably you would have to avoid growing a beard or something like that for a full face scan to work. Or is just specific features like the relative position of eyes, nose, etc? Scanning of irises and fingerprints is not so at risk from such problems.

work by comparing the face that's being scanned with a database. The parameters include the distance between eyes, relative positions of eyes to nose and mouth, relative alignments of ears with other reference points etc. There are literally dozens of comparison possibilities. Look at a picture of a human face and cover one half with a sheet of paper. Then move the paper to the other half - it's almost like looking at two different people. The differences between the two halves of a face are far more marked in some people than others, but they're there.

Complete facial symmetry is almost unknown, which is why facial scans are a good way of identifying individuals. We scan faces all the time, and we're capable of making incredibly subtle judgments in a few seconds. Most people are capable of recognising a person they only met once, even after quite long periods, and all of us carry huge databases around in our heads. How many times have you had that "I know that face" feeling?

Computers can do the same thing, except in their case "I know that face" can mean "I can tell it apart from millions of others, and provide you with the person's name, address, nationality, date of birth, distinguishing marks, criminal record (if any), colour of eyes and hair, and the date on which he/she last entered and left this country".

If you want to see how good Biometric scans are, google a few Las Vegas casino sites. They are able to identify any visitor that has walked through their doors during the past few years. (and get them shown to the exit if identified as undesireable)
