how do cashpoint machines work?

A cashpoint machine is like a computer-controlled safe. You type in your Personal Identity Number (PIN), which is checked with your bank, and then it gives you the money you ask for.

The cash-dispenser mechanism counts notes. It also has a thickness sensor to detect when two notes are stuck together. These are diverted to a rejects bin, along with any other damaged or torn banknotes.

The cashpoint records all transactions in its "journal". A printed copy of this journal is kept and you can see it if you have a problem.
