Wot's an ID card

Wot's an ID card? Later today, we'll find out, but Auntie has some hints:

The cards will be compulsory for foreign nationals and those working airside in Britain's airports, such as baggage handlers and cabin crew.

The rollout to students, is, according to BBC political reporter Norman Smith, part of a government strategy to offer cards to those most willing to accept them.

He says the thinking is that younger people will be more receptive to carry ID cards, because they will make it easier to open a bank account.

Hmmm. The government's already tried an investment-card-masked-as-something-a-bit-cool, and it ended badly.
