To open a bank account you need a fixed address and proof of ID in the form of a passport or driving license.

In the last year several thousand people have had bank accounts closed under the presumption of being a "politically vulnerable person", one example was a teacher who went to volunteer in Ukraine for while.

If your bank account is overdrawn you get fees and are unable to use your card.

My mother is 85 and doesn't understand ATMs, never mind online banking. The decreased access to cash has left her confused, and when stressed she can't remember her pin number.

Cops have been able to track people down with just unique shirts bought online.
