Is this the end of cash as we know it?

Significant technological advances mean you could soon be paying for your coffee or paper with an Oyster-style smart card or even your mobile phone. Simon Wilson reports on the rise of digital money.

What is digital money?

In short, an electronic payment method that doesn't involve cash or the magnetic-strip swipe cards we're all used to. Best known is the Oyster card used on London's tubes and buses, a classic example of a successful contactless or "wave-and-pay" solution. For years, futurologists have been making predictions about the demise of physical cash, but, in reality, that's not going to happen soon, even if Londoners finally start using their Oyster cards to buy newspapers and coffees. Notes and coins might make up only a small fraction of the money in circulation in rich countries, but judging by transaction volumes, rather than value, cash is still king. For example, in the UK, 89% of transactions under £10 are for cash.
