ePassports are no good for 6-12 year olds

Last weeks ePassports seminar out at the Reserve Bank's Note Printing works in outer Melbourne was very interesting, if only because of the revelation that
our new electronic passports are going to be less than perfect.
They'll have a scanned picture of us on their chip, which will be checked by
an automated face recognition scanner at the airport.
(I assume how it will work will be that the machine will compare the face of the passport holder with the scan stored in the passport chip).
Trouble is, the faces of kids aged between 6 and 12 change quite a lot as they grow.
So, as the senior official from the Department of Foreign Affairs freely admitted, these ePassports are likely to be pretty useless and the customs or immigration officials will have to fall back on the traditional checks.
Of course, the whole question of identity fraud remains very serious and I want to make it very clear that I'm not questioning the need for ePassports.
After all, there are sites on the web like fakeguruid.com advertising Australian drivers licenses made to order.
