Pix transfers money between accounts in seconds, at any time. At checkout, the buyer scans a QR code or copies a code, pays through their bank's app, and confirmation comes back almost immediately, which allows the product to be released right away.

For the seller, the strong point is risk: Pix has no chargeback. Once paid, the amount can't be pulled back through a card dispute.

The limit is geographic. Pix only exists in Brazil, so it solves the domestic operation and doesn't replace a card for international sales.
