Why Is My QR Payment Not Working?
First check the QR type, camera permission, identity verification, and available balance. Peanut supports compatible Mercado Pago merchant QR codes in Argentina and supported Pix merchant QR codes in Brazil. If a payment is missing, save evidence instead of assuming that an error status proves a refund.
Fix a QR Payment Problem
- 1
Check the QR type
In Argentina, use a compatible Mercado Pago merchant QR, not MODO or Cuenta DNI. In Brazil, use a supported Pix merchant QR. If the payer has no QR, pay their Pix key instead: Send → Bank → Brazil. Peanut does not support every QR format.

Check the camera
Allow camera access, clean the lens, keep the whole code in frame, and avoid glare. Ask the merchant for a fresh code if it expired.
- 3
Check verification and balance
QR payments require the relevant verification and enough available balance. Review the exact error shown in the app.
- 4
Do not retry an uncertain payment
If the first attempt may have settled, do not immediately pay again. Save the app confirmation and ask the merchant for its receipt or transaction history.
- 5
Send evidence to support
Share the amount, merchant, approximate time, app screenshot, merchant receipt, and any second-payment receipt. Support can confirm settlement.
When the Merchant Says It Failed
A terminal can display failure even when Pix settled. The app status and terminal message must be checked against the payment record. If settlement confirms that the merchant received the payment, a completed QR payment cannot be reversed by Peanut. If the customer paid a second time, the merchant must return the duplicate.
A failed attempt may also show in the app even though no money left the balance. Support can check the ledger. Do not promise a refund or timeline until that review is complete.
FAQ
Does Peanut work with every QR code?
No. It supports compatible Mercado Pago merchant QR codes in Argentina and supported Pix merchant QR codes in Brazil. Other QR networks may not work.
What if the app says completed but the merchant disagrees?
Collect the app confirmation and merchant receipt, then contact support. A status alone is not enough to resolve the settlement.
What if the app says failed?
Do not assume that a refund has completed. Check the balance and send the transaction evidence to support if anything is missing.
Should I scan and pay again?
Not while the first attempt is uncertain. Confirm settlement first to avoid a duplicate payment.
