Well that's OK then - right up to the point where some tosser loses it, leaves it on the train, loses his copy on a USB stick or decides to sell out.
The point of the biometrics and the checksum on said card is so nobody else can use it. Of course that will only work if the biometrics are properly checked upon production.
I agree this does get people hot under the collar, but I think its more about being forced to accept another ID rather than having the choice to adopt it. What is more infuriating and fundamentlly wrong is the government proposal that we all pay for said ID Cards ( I bet some bright spark will offer to fund these cards in return for advertising on the back).
I do however think that if the idea was thought through properly it could be implemented so that you would only ever need a single ID card right from your library card to your airside pass - but I wont hold my breath.
Cheers
