Why PIX can't be taken back
PIX is wonderful for everyday life: it moves money in seconds, any time, day or night. But that speed cuts both ways. Once you confirm a transfer to a scammer, the money is gone in seconds — it lands in a "conta-laranja" (a mule account opened in someone else's name) and is moved on before anyone can stop it.
There is a refund process at the bank, called the MED, but it only works if the money can still be traced — and it recovers just a small part of what's stolen. In other words: with PIX, stopping the payment before you send it is almost the whole game.
What to do: treat every PIX the way you'd treat handing over cash. Before you confirm, ask yourself: do I really know who is receiving this, and why? If anything feels rushed or strange, stop — a real payment will still be there in ten minutes.
Threat examples
Don't worry about sending the PIX now — if anything's wrong you can just request a refund afterwards, it's automatic.
