Biometrics will come, who will care about privacy

Arriving at the new Terminal 5 at Heathrow airport I saw some extra installations (and extra lines) for iris scan immigration. Arriving at 4 am in the morning they were closed and there were not queues - but I could see that it is very attractive at other times of day when queues are long. On the official website they claim that border control will be down to 20 seconds. There is a more detailed document on the schema - I saved the document to have it in 10 years when we will have a very different view on privacy.
