Identity Documents Bill

I am sorry for intervening again, but as the House will appreciate, the subject is rather close to my heart. I understand entirely that the document will not be useable for travel purposes once the Bill has received Royal Assent, but I understood the right hon. Lady to say that it would not be valid in offering any proof of identity. Just before that, she said that it would be illegal. I am trying to ascertain whether using this document, which has my fingerprints and photo and is more authentic than my passport, would make me a criminal were I to use it for other purposes, such as opening a bank account.
