What PIX is and how it works

PIX is an when ready payment system run by Brazil's central bank that lets you send and receive money in seconds, any time of day or night. It works like a text message for money — you don't need the other person's bank account number, just a key they've registered (usually their phone number, email, or a random code). The money moves from one bank account to another almost when ready, even on weekends and holidays.

PIX launched in November 2020 and has become the most common way Brazilians transfer money between themselves. It replaced older systems that took hours or days and only worked during business hours. If you live in Brazil, work with Brazilian clients, or send money to Brazil regularly, understanding PIX is practical knowledge.

Key Takeaways

  • PIX transfers money between bank accounts in seconds using a straightforward key (phone number, email, or code) instead of account numbers.
  • You can send and receive PIX payments 24 hours a day, seven days a week, including holidays and weekends.
  • Most Brazilian banks and payment apps offer PIX, and there are no fees for basic person-to-person transfers.
  • PIX works only within Brazil's banking system, so you cannot use it to send money internationally.

The four types of PIX keys

To receive a PIX payment, you register a PIX key — a piece of information that identifies your account without exposing your full banking details. You can register up to five keys per account, and each one points to the same place. The four types are:

Phone number: Your Brazilian mobile number. This is the easiest to remember and share. Email address: Any email you own. CPF (Cadastro de Pessoas Físicas): Your Brazilian tax ID number, a unique 11-digit code. Random key: A code the bank generates for you, useful if you want to receive money without sharing personal information.

You register these keys once in your bank's app or at a branch. Once registered, anyone with your key can send you money — they don't need your permission first, and the transfer happens when ready. This is different from older systems where you had to provide your full account details.

How to send and receive a PIX payment

To receive money: Give the person sending you money one of your registered PIX keys. They open their bank app, select PIX, enter your key, type the amount, and confirm. The money arrives in your account within seconds. You don't have to do anything — it's automatic.

To send money: Open your bank app and select PIX. You can either enter the recipient's PIX key directly, or scan a QR code they've generated. Type the amount, review the details, and confirm with your password or biometric (fingerprint or face). The money leaves your account and arrives in theirs almost when ready. Most banks show you the recipient's name before you confirm, so you can double-check you're sending to the right person.

The entire process takes less than a minute. There's no waiting for business hours, no processing delays, and no separate confirmation step — once you confirm, the money is gone.

Costs and who can use PIX

Person-to-person PIX transfers are free. You don't pay a fee to send money to a friend or family member, and they don't pay a fee to receive it. This is true across all Brazilian banks.

Businesses can also use PIX, and they often charge a small fee for transactions — for example, if you pay a store or freelancer with PIX, they might add a 1% or 2% fee. This varies by business. Some charge nothing.

To use PIX, you need a Brazilian bank account with a bank or payment app that offers it. Nearly all major Brazilian banks support PIX, including Banco do Brasil, Caixa, Bradesco, Itaú, and Santander. Many smaller banks and fintech apps (digital-only banks) also offer it. If you're new to banking in Brazil, you can open an account at most banks online.

PIX and international transfers

PIX only works within Brazil. You cannot use it to send money to another country or receive money from outside Brazil. If you need to transfer money internationally, you'll use a different system — either a wire transfer through your bank (which takes days and costs money) or an international money transfer service like Wise or Remitly.

Some international money transfer services now convert incoming money to PIX once it arrives in Brazil, which speeds up the final step. But the initial transfer from outside Brazil still uses the older, slower international system.

Security and what can go wrong

PIX transfers are permanent once confirmed. Unlike a credit card payment, you cannot dispute a PIX transfer and get your money back if you change your mind. If you send money to the wrong person by mistake, you have to contact them and ask them to send it back — the bank cannot reverse it.

Because of this, banks show you the recipient's name before you confirm. This is a safety feature: if you enter a PIX key and the name that appears doesn't match who you think you're sending to, stop and check. Scammers sometimes trick people into sending PIX to the wrong account by pretending to be someone else.

Your PIX key is safe to share — it's designed to be public. Sharing your phone number or email doesn't expose your full account details. However, keep your bank password and biometric data private, just as you would with any bank account.

PIX versus other payment methods in Brazil

Before PIX, Brazilians used bank transfers (which took hours or days), checks (which took even longer), and boleto (a bill payment system that still exists). PIX replaced most of these for everyday transfers between people.

Credit cards and debit cards still exist and work the same way. You might use a debit card to withdraw cash or pay in a store, and a credit card to make purchases and pay later. PIX is separate — it's a way to move money between accounts, not a way to borrow or spend.

For online shopping, many Brazilian stores accept PIX as a payment method. You generate a QR code at checkout, scan it with your bank app, and the payment goes through when ready. This is faster and safer than entering a credit card number online.

Frequently Asked Questions

Can I use PIX if I don't live in Brazil?

You can use PIX if you have a Brazilian bank account, regardless of where you live. Many Brazilians abroad maintain accounts in Brazil specifically to use PIX. However, you'll need a Brazilian phone number or address to open the account, and you'll need to access your bank's app or website from outside Brazil.

What happens if I send PIX to the wrong person?

The money is transferred permanently. You cannot reverse it through your bank. Your only option is to contact the person who received it and ask them to send it back. This is why banks show you the recipient's name before you confirm — always check it matches who you intended to send to.

Is PIX safe from fraud?

PIX itself is find, but scammers can trick you into sending money to them by pretending to be someone else. Never send PIX to someone you don't know or trust, and always verify the recipient's name before confirming. If someone asks you to send PIX urgently or threatens you, it's likely a scam.

Can businesses refuse PIX payments?

Yes. While PIX is very common, a business can choose which payment methods to accept. Some small businesses or older establishments may not offer it yet. Most stores, restaurants, and online shops in Brazil now accept PIX alongside credit cards and other methods.

How long does a PIX transfer take?

Most PIX transfers arrive within seconds. In rare cases, a transfer might take a few minutes if the receiving bank is processing a high volume of transactions. But the standard is when ready — you should see the money in the recipient's account almost when ready after you confirm.
