Brazil’s central bank will authorize a payments system involving Facebook Inc’s (FB.O) WhatsApp messaging service, to send money and make payments via chats, as long as all rules are respected, director Joao Manoel Pinho de Mello said on Monday, Reuters Reported.

“We view the entry of ‘big tech’ as a huge opportunity. Everyone can participate. We will allow it, no problem. People can take whatever path they want, (do) whatever initiatives they want,” as long as rules and regulations are met, he said during a live online event hosted by Genial Investimentos.

The central bank suspended the newly launched WhatsApp payment service last month and said it is analyzing whether the service can operate safely in terms of data protection and competition.
