We've not had to provide the identification.
Now we will have to provide photo ID, which has a service number and your name on it. There was no prescribed information before. We would not bring, for example, bills or anything with our identification on it. We have our own driver's licences overseas, so we wouldn't have that information with us for security reasons.
You're not precluded from bringing your driver's licence in all situations, but there are certainly situations where you wouldn't want any personal information with you.
