Cash is king in the age of surveillance capitalism (coupled with paper receipts)
One of my children has a book about forensics with the simple phrase 'every contact leaves a trace' on its back cover.
I should be able to choose to purchase with cash and without having to give any personal details the vast majority of goods and many services.
Emailed receipts build up the same plethora of personal data that loyalty store cards collect.
Many people will say that is perfectly acceptable, but may not be fully aware of the power of that data when it comes to profiling consumers and the insights it gives those collecting the data into their (very personal) lives.
Biting the hand that feeds IT
