PIX Explained: How It Works, Limits, MED Refunds (2026)

Last verified: 6 October 2026. Figures come from the Banco Central do Brasil and from reporting on its published statistics; they are updated regularly, so check the Central Bank's Pix statistics page for the latest numbers.

If you spend any time in Brazil, you meet Pix within minutes. It is the QR code on the counter of a street-food stand, the "send me your key" message between friends, the way a landlord gets paid and the way a government benefit reaches a family. Launched by the central bank in November 2020, Pix has become the default way Brazilians move money, and it is widely studied by other countries building their own instant-payment systems. This guide explains what Pix is, how it works in practice, how safe it is, what its limits are, and why it matters when you read about payments in Brazil in 2026.

What is Pix?

Pix is Brazil's instant payment system. It was created and is operated by the Banco Central do Brasil as a piece of public infrastructure, and banks, fintechs and other regulated institutions connect to it so that their customers can use it. Money moves between accounts in a matter of seconds, 24 hours a day, every day of the year, including weekends and holidays. For individuals, sending and receiving a Pix payment is free of charge.

The key difference from older Brazilian bank transfers, which were tied to banking hours and settlement windows, is that Pix is always on and nearly immediate. The key difference from a card is that the money moves directly from one account to another, without a card network in the middle.

A short history

2018–2019 – the central bank begins designing an instant-payment system as part of its payments agenda.
3 November 2020 – a restricted pilot starts with a small share of bank customers.
16 November 2020 – the official, full launch, with Pix running 24/7 for every customer who registers a key.
16 June 2025 – Pix Automático goes live, allowing recurring debits for bills and subscriptions with the payer's authorisation.
2025–2026 – new security rules and new features, including instalment-style payments (Pix Parcelado) offered by several banks and fintechs, and an extended window for contesting returns under the special refund mechanism.

How Pix works step by step

1. The Pix key

Instead of typing a branch number, an account number and a bank code, you register a Pix key that points to your account. A key can be your CPF (the individual taxpayer number), your mobile number, your e-mail address or a random key generated for you. Companies can use their CNPJ. Individuals can register up to five keys per account and companies up to 20, a given key can be linked to only one account at a time, and you can move a key from one bank to another.

2. Paying with a key or a QR code

To pay, you choose "Pix" in your banking app, enter the recipient's key (or scan a QR code, or paste a "copia e cola" code) and confirm. You see the recipient's name before you approve the payment, which is an important checkpoint against mistakes. Static QR codes carry a fixed receiver, while dynamic QR codes are generated for a specific charge, such as a shopping basket or an invoice.

3. Settlement

The payment reaches the recipient within seconds. There is no "pending" state that depends on opening hours. That immediacy is also the reason security rules matter so much, as we explain below.

4. The receipt

Both sides get a digital receipt with a transaction identifier. Keep it: it is your proof if there is ever a dispute.

What makes Pix different from cards and bank transfers

Cost. Free for individuals. Merchants pay far less than they usually would on a card, which is a major reason small businesses adopted it so quickly.
Speed. Seconds, not days.
Availability. 24/7/365.
Simplicity. A key or a QR code instead of banking details.
Inclusion. It runs on a phone and works with accounts that do not have a credit card attached, which helped bring many people into digital payments for the first time.

Pix in numbers

According to the Central Bank and to reporting on its statistics:

More than 170 million individuals had used Pix by January 2026, around 80% of the population.
More than 800 institutions take part in the system.
In 2025, Pix handled almost 80 billion transactions, about 25.7% more than the year before, moving well over R$ 35 trillion.
In August 2026, Pix passed 8 billion transactions in a single month for the first time.
On 4 September 2026 it set a daily record of 318,073,816 transactions, worth about R$ 186.9 billion, on a day that coincided with salary payments for many formal workers.
In the Central Bank's May 2026 Financial Stability Report, Pix accounted for roughly 29% of retail payments in the previous six-month period.

Newer features: Pix Automático and Pix Parcelado

Pix Automático lets a payer authorise a company to charge them recurring amounts, such as a utility bill, a gym membership or a subscription, without having to approve each charge manually. It launched on 16 June 2025 and adoption has been growing month after month, although it started from a small base.

Pix Parcelado allows a buyer to pay in instalments while the seller receives the money up front, with the financing handled by the bank or fintech. Several large banks and payment apps now offer it, and each institution sets its own conditions.

Pix security: limits, refunds and good habits

Because Pix is instant and irreversible by default, the Central Bank has added protections over time. The main ones are:

Night-time limit. For individuals, institutions apply a limit on Pix transfers during the night, in principle between 20:00 and 06:00. The default is R$ 1,000 per transaction. You can usually adjust it in your app, and the rule was introduced because crimes such as "sequestro relâmpago" (a very short kidnapping to force transfers) and electronic scams concentrate in those hours.
Special Refund Mechanism (MED). The Mecanismo Especial de Devolução helps people try to recover money sent through Pix in cases of fraud, scam, crime or operational failure. It does not cover simple user mistakes (such as typing the wrong key) or commercial disputes with no sign of fraud. A payer has 80 days from the original Pix to ask their bank, and can do so inside the bank's own app. The bank has about seven days to analyse the case and may block the funds in the receiver's account meanwhile; if fraud is confirmed, the return is due within about 96 hours, in full or in part depending on what is still in the account. Since February 2026 the mechanism can also follow the money across several accounts, not just the first one. From 1 September 2026 the Central Bank extended from 30 to 80 days the time a receiver has to contest a refund made through the mechanism. Recovery is never guaranteed, so report immediately.
Per-transaction and daily limits. Each bank sets limits, which you can normally raise or lower in the app. Lower limits are a simple way to reduce exposure if your phone is stolen.
Name check. Always read the recipient's name before confirming.

The most common Pix scams

Fake QR codes pasted over a legitimate one.
"Wrong transfer" messages in which someone sends you money and then asks you to return it to a different account.
Fake customer-service calls or messages that ask you to "confirm" a payment or install a remote-access app.
Fake sales and fake fees, where you are asked to pay something to "release" a prize, a loan or a balance.

The rule that protects you in almost every case: no real institution will ever ask for your password, your token or a Pix payment to unlock your own money.

Pix and online betting

Pix became very popular as a way to fund online betting accounts in Brazil because deposits were instant and withdrawals came back quickly. That changed on 25 September 2026, when Medida Provisória nº 1.394/2026 prohibited fixed-odds betting nationwide and told banks and payment providers to process only the transactions needed to wind betting accounts down. According to the Senate's summary of the measure, banks and payment institutions may not process or enable betting transactions except those needed to wind accounts down, and the Central Bank must put in place a mechanism to reject instant payments linked to prohibited betting. Using Pix to fund betting in Brazil is therefore not possible while the measure is in force, and Congress may still change it. Our guide on the betting ban explains the timeline and what happens to balances.

It is worth stressing what Pix is and is not. Pix is a payment rail, like a bank transfer: it is neutral and it is not a gambling product. It also does not create a legal obligation for anyone to accept it. And if anyone asks you to send a Pix payment to deposit into a betting account today, treat it as a serious red flag.

Pix outside Brazil

Pix is operated through Brazilian institutions and, for ordinary users, it moves reais between Brazilian accounts. If you do not hold an account in Brazil, you should not assume you can use it, and you should check with your own bank or payment provider. Other countries have studied Pix as a model for their own instant-payment schemes.

Frequently asked questions

Does Pix cost anything?

For individuals, sending and receiving Pix is free. Businesses may pay their provider a fee, which is generally lower than a card fee.

Can I use Pix at night?

Yes, Pix works 24/7. For individuals there is a default night-time limit of R$ 1,000 per transaction between 20:00 and 06:00, which you can usually change in your banking app.

Is a Pix payment reversible?

Not automatically. If you were the victim of fraud or a scam, contact your bank immediately and ask about the Special Refund Mechanism (MED), which has an 80-day window from the original payment. If you simply sent money to the wrong person by mistake, the MED does not normally apply: contact your bank and, where possible, the recipient.

Do I need a Brazilian bank account?

Yes. Pix works through accounts held at institutions authorised by the Central Bank, and you register keys such as your CPF or phone number in your own banking app.

What is a "copia e cola" code?

It is a text string that contains the payment instructions of a QR code. You can paste it in your banking app instead of scanning the code.

Can I use Pix to fund a betting account in Brazil today?

No. Fixed-odds betting is prohibited under MP 1.394/2026 and payment institutions are limited to winding down existing betting transactions.
