To make a deposit, click on "Deposit Now" at the top of the page near your balance.

PIX chosen as the payment method will have to be a CPF (Cadastro de Pessoas Físicas).

Enter your CPF, and click on "Proceed".

You will then be directed to a result or conclusion page, in which you have to scan the QR Code or copy and paste the PIX.

This implies that the code that is in the QR code is copied, enabling one to copy-paste the same through the "Pix Copy and Paste" function in the Pix section of the app provided by the bank or through an online bank service.
