What Is PIX?
PIX is Brazil's instant payment system, launched by the Banco Central do Brasil (Brazilian Central Bank) in November 2020. It allows individuals and businesses to send and receive money instantly, 24 hours a day, 7 days a week — including weekends and holidays. PIX has rapidly become one of the most widely adopted payment systems in the world, transforming how Brazilians handle everyday transactions.

Understanding PIX Keys
A PIX key is an alias that identifies your bank account. Instead of sharing your full bank details, you share a single key. You can register up to 5 PIX keys per personal account and up to 20 for business accounts. The available key types are:
- CPF/CNPJ: Your individual or company tax number
- Phone number: Your mobile number registered with the bank
- Email address: A valid email you control
- Random key (Chave aleatória): A system-generated alphanumeric code for privacy
How to Register a PIX Key in Your Banking App
- Open your banking app and navigate to the PIX section.
- Select "My Keys" or "Register Key".
- Choose the type of key you want to register (CPF, phone, email, or random).
- Confirm your identity using your app password or biometrics.
- If using phone or email, validate via a confirmation code sent to that contact.
- Your key will be active and ready to use within minutes.
How to Send and Receive Money with PIX
Sending a PIX Transfer
- Go to PIX → Send in your app.
- Enter the recipient's PIX key, QR code, or bank account details.
- Type the amount and an optional description.
- Review the recipient's name and bank — always verify before confirming.
- Authorize with your password or biometrics. The transfer completes instantly.
Receiving a PIX Transfer
Simply share your PIX key with the sender. You can also generate a PIX QR code in the app — ideal for businesses or when requesting a specific amount. Funds appear in your account within seconds.
PIX Safety Tips
- Always confirm the recipient's full name before sending any transfer.
- Be wary of "PIX scams" — legitimate entities will never ask for a PIX transfer to unlock prizes or unblock accounts.
- Use the Scheduled PIX feature for recurring payments to reduce manual errors.
- Set daily and nightly transfer limits appropriate to your typical usage.
PIX Limits and Controls
Banks allow you to configure your own PIX limits for added security. You can set separate limits for daytime and nighttime transfers. Changes to increase limits often require a waiting period of up to 24–48 hours for security reasons. Reductions, however, take effect immediately.
Why PIX Matters for Digital Banking
PIX has made mobile banking apps the central hub for financial life in Brazil. By consolidating instant transfers, bill payments, and QR code transactions in one place, banking apps have become essential daily tools — not just a convenient extra. Understanding how PIX works inside your app is the foundation of confident digital banking.
