What is PIX and why it is popular in Brazil
PIX is a national instant transfer system launched by the Central Bank of Brazil. It works 24/7/365, transferring money between banks and fintech wallets within seconds. For individuals, transfers are most often free, businesses pay minimum tariffs to providers. Due to its simplicity (keys, QR codes) and speed, PIX quickly supplanted classic methods like DOC/TED and boleto in a variety of scenarios - from personal transfers to payment in stores and online.
How the PIX Works - in Simple Terms
1. Identification through "keys" (chaves PIX).
The user binds one or more "chave" to the account: phone number, e-mail, CPF/CNPJ (tax ID) or random code. It is enough to know the recipient's key - and the money flies away to him instantly.
2. QR codes: static and dynamic.
Static - convenient for a fixed wallet (for example, a small business); the buyer enters the amount himself.
Dynamic - generated for each sale: contains amount, purpose and metadata (order ID).
3. PIX Copia e Cola.
Alternative to QR: a long payment string that can be copied and pasted into the bank's application.
4. Instant confirmation.
The sender sees the debit from the account, the recipient sees the credit and the transaction check almost immediately.
5. Integration into the cash register.
Banks/fintechs give APIs, so online stores and applications show the QR/PIX line right at the payment stage.
Why PIX Became So Popular
For people (individuals)
Fast and free. Transfers between any banks go in seconds, without commissions in ordinary scenarios.
Convenience. No details are needed: the recipient's phone or e-mail is enough.
Everywhere and always. It works 24/7 - both day and night, on weekends and holidays.
Payment for purchases. No need for a card: scanned QR in the store - and you're done.
For business
Low cost of reception. Lower than card acquiring; there is no classic "chargeback" as in cards.
Instant liquidity. Money in the account instantly - convenient for turnover and cashout of couriers/freelancers.
Simple integration. Generation of dynamic QR, payment matching by order ID, auto-parsing "copy-insert."
Broad scope. Almost every customer in Brazil has a PIX-enabled bank/fintech.
For the economy and the state
Reduce cash flow and collection costs.
Transparency and competition. Uniform rules from the regulator stimulate fintech competition and reduce the monopoly of cards.

Robberies/extortion.
What to do: limits on night transfers, hidden notification mode, the ability to quickly reduce the limit in the application.
Bank account theft.

P2P: repay, transfer to relatives, split restaurant bill.
P2B (shops): pay offline by QR at the checkout or sign.
Online shopping: e-commerce shows dynamic QR, the order counts instantly.

Public services/bills: taxes, fines, utilities can be paid through the PIX (where supported).
How to Start Using the PIX (Step by Step)
1. Open an account with a bank/fintech that supports PIX.
2. Register "chave PIX" - phone, e-mail, CPF/CNPJ or random key.
3. Try a P2P transfer: send 1 real to a friend by key or scan his QR.
4. In-store payment: scan dynamic QR, check recipient name and amount, confirm.
5. For business: connect PIX reception from your bank/PSP, generate dynamic QRs and receive payment notifications.
