If anyone tries to put scans of my iris or prints of my fingers in an ID card I will fight them off. Someone nicking my credit card number is one thing - I can get another. But I've only got one set of fingerprints and one set of irises to last me a lifetime. Any database containing this information would be an Aladin's Cave for hackers and organised criminals. Centralised databases are insecure by design.
The Government is dangerously out of line on the issue of ID cards and sadly I can see the UK sleepwalking into this one. They won't listen to even its own MoD information security specialists, or international expert on information security Bruce Schneier.
As a Brit overseas, I'll not be watching this from afar and will stay well clear if it is introduced.
