I can remember having a Post Office account when I was young. It was the first ‘bank’ account that I ever had and its balance was controlled not by some hidden computer system, but by a balance manually written in a book, by the nice lady behind the counter.

Nowadays, banking and financial services is one of those industries that couldn’t survive without technology. From verifying who you are, to keeping track of your money, to payments, everything relies on IT systems that have to be kept running. In fact, the only time you can escape technology is when you withdraw money from an ATM (another computer) and physically hand it to someone else.
