This functionality combines the speed of Pix with biometric validation, allowing payments to be confirmed without friction, without passwords, and with fewer steps.
For companies operating in Brazil, this is not just a technological improvement—it’s a direct opportunity to optimize checkout and increase conversions.
What is Pix with Biometrics?
Pix with biometrics is a payment method where the user:
Initiates a Pix payment (QR code or key)
Confirms the transaction using facial recognition in their banking app
Instead of entering passwords or codes, users simply validate the payment with their face in seconds.
Result: a much faster and more natural process.
Why Does Pix with Biometrics Improve the Payment Experience?
In ecommerce, every additional step reduces conversion. Pix already removed many friction points, but biometrics takes this even further.
