WhatsApp launched in-app payments in Brazil, after testing a beta versión in India, on Monday in the blog post (through TechCrunch).
Payments can be made via the Facebook Pay program, which Facebook's parent company said last year to Instagram, Messenger, Facebook, and ultimately WhatsApp.
"WhatsApp Payments are beginning to be made available to people throughout Brazil today and we look forward to making them all available as we move forward," said the company in the post.
WhatsApp says their digital payments are an open platform that will make it possible in future to add more partners.
Consumers do not pay the fees for using the payment service, but retailers are paid a fee for handling the payment.
Users must link a credit or debit card to their whatsApp account, and either a fingerprint or six digit PIN is used to secure transactions.
The business says it is going to help the Bank of Brazil, Nubank and Sicredi credit or debit cards and it works together with Brazil's Cielo payment processor.
WhatsApp has for a long time been involved with peer-to - peer digital payments. In 2018, it launched a shutdown beta in India, which many believed to be the first WhatsApp official site.
But as TechCrunch reports, Facebook has answered a range of regulatory questions in India and its history there has been a bit complicated, and the 2017 proposal for free access to Facebook has increased controversy and led to digital colonialism allegations.
WhatsApp was purchased by Facebook in 2014 for about $19 billion. Since February, there were more than 2 billion users in the messaging service.
