NEWS of the death of cash has always been exaggerated. But the wounds being inflicted on notes and coins multiply. On March 17th Facebook, the world’s biggest social network, announced that in America its instant-messaging app will soon allow users to send each other money just as easily as texts and photos. All they need to do is link their debit cards to their Facebook account, tap on a dollar sign in the app, type in the amount and press send.

Facebook is not the first to enter the market for free person-to-person (P2P, as geeks have it) payments. In November, for instance, Snapchat, a messaging app that lets users send each other photos that disappear after a few seconds, introduced a service called Snapcash. It competes with Venmo, a popular money-transfer app owned by PayPal, an online-payments firm. In Asia, messaging apps, such as WeChat and Line, have offered P2P transfers for some time.

The incumbents don’t have to worry too much, at least for now. In contrast to Snapcash and Venmo, Facebook’s service does not make instant payments: the money only arrives after a few hours or even days, depending on how quickly users’ banks act. This is because money is not transferred between accounts managed by the social network, but goes through conventional payment channels from one bank account to the other.

Still, Facebook’s new offering is further proof that technology firms are moving onto banks’ turf. Next month Apple will begin selling its smartwatch, which lets consumers pay by waving their arm at the till; this will help the firm’s new contactless payment service, which already accounts for two of every three dollars spent in America by gesturing with a smartphone or a card. Google recently bought Softcard, a mobile-payment service, to boost its own payment app and catch up with Apple. Meanwhile Naver, South Korea’s biggest online portal, will launch a new mobile-payment service in June.

Were Facebook to expand its offering internationally and make it truly instant, the impact could be huge. Facebook has 1.4 billion members, its messaging service 500m users. Many doubtless send remittances across borders; some are probably unbanked. The regulatory and logistical challenges of serving such customers would be huge. Banks struggle to profit from them. Then again, that is just the sort of challenge tech firms relish.

Resumen por Clara Serra

No se trata, aún, de la muerte del dinero efectivo, pero los intentos de lograrlo se multiplican. Facebook acaba de anunciar que su programa de mensajería pronto permitirá (en Estados Unidos, inicialmente) que sus usuarios se envíen dinero entre si con la misma facilidad con que se envían fotos o mensajes. Todo lo que requieren es registrar sus tarjetas debito en Facebook, escribir la cantidad en el app y teclear “enviar”.
