Nubank has introduced a tap-to-pay feature for in-store transactions using Brazil's Pix instant payments system, allowing customers with an Android device to make contactless payments. Users can choose to pay from their account balance or credit, with an option for up to 12 instalments, and can easily add a shortcut to their home screen for convenience. Pix, launched in late 2020, has quickly become the most popular payment method in Brazil.
