The government is still persisting with it's plans for ID cards. This is of course a scaled back version of the small-pilot scheme, but they still want to fingerprint and face-scan everyone in the UK. This data will be stored in the National Identity Register, and then duplicated in part or in full so that car parks, trains, delivery couriers, Internet hackers and others can get copies of it.
Even if you haven't figured out that this is an instant infringement on your liberty, you should be able to see that it's an instant way to lose all your privacy, lose all your personally identifying information and watch your government demonstrate it's utter ineptitude.
Remember: All your life you've been told by your teachers, your parents, banks and even the government that you should protect your identity - don't tell people unique things about you (like your name, your home address, your bank account number, etc). Don't forget this when the government asks you to give up everything unique about you for this scheme. No2ID.
