That's great news! WhatsApp users in Brazil can now use the app to make payments to merchants. This feature was introduced in June 2020 and is called WhatsApp Pay.

To use WhatsApp Pay, users in Brazil need to link their WhatsApp account to a debit or credit card issued by a participating bank. They can then make payments directly from within the app to merchants that have also registered for the service. Payments can be made for goods and services, as well as to friends and family.

WhatsApp Pay in Brazil is powered by Facebook Pay, which is Facebook's payment system. The service is free for users, and there are no fees for merchants to receive payments. However, WhatsApp may charge fees in the future for some types of transactions.

Overall, WhatsApp Pay provides a convenient and secure way for users in Brazil to make payments without having to leave the app. It also benefits merchants by providing them with a new way to receive payments and connect with customers.
