They can ask someone to ascertain their identity under the act (as I understand it) - but I am under no obligation to carry any form of id with me to prove who I am to the police - if I happen to have my passport/driving licence with me as a form of id I would show it to them but I am not aware of a law that requires me to carry it on the off chance they think I am a terrorist. Happy to be proved wrong.
