We are constantly being told that we are on the cusp of a cashless society. The financial services industry would certainly like to see it that way. We are being enticed with contactless cards, mobile phone payment apps, and methods of bank transfer: all, apparently, for our convenience.

But as Ross Clark argues in this compelling new book, it is not in our interests to surrender the right to use cash. Commercial interests want us to pay electronically in order to collect valuable data on our spending habits, while governments would love us to move to cashless payments in order to control the economy in ways which suit it, not us.

If we choose to pay electronically, that is one thing, but we will regret it if we do not defend the right to pay with cash.
