Digital wallets have a chicken-and-egg problem: Square, Twitter co-founder Jack Dorsey's new company, provides small businesses with an appendage that plugs into the headphone jack of a mobile phone and allows merchants to swipe cards and take payments. But Dorsey's real goal is removing cards altogether. Every merchant using Square to take card payments can also take payments directly from the Square app on customers' phones — and thanks to a high-profile deal with Starbucks, that's now quite a few customers.

Every company has its own, non-transferrable, digital wallet app. In some of that fragmentation should end as Vodafone, EE and O2 form a mobile wallet service, "Weve". But the days of digital wallets being as straightforward as credit cards seem a long way off.
Despite news stories about bitcoin being illustrated with shiny metallic discs, bitcoins are simply chunks of data on a hard drive that can be bought with "real" money or them by getting a computer to chug through some complex maths.
