Why was a data authentication requested during my purchase?

In some countries, especially in Europe, data authentication is mandatory for online purchases. This requirement is part of the 3DS2 protocol, created to increase transaction security, reduce fraud, and ensure that the cardholder is truly authorizing the purchase.

How does this authentication occur?

The process is simple and fast.
At the time of purchase, you enter your card data and click to complete the purchase.
The payment request is sent to your card's issuing bank.
The bank analyzes the transaction and, if it identifies the need for additional verification, requests authentication to confirm the identity of whoever is making the purchase.
This authentication occurs on a new screen sent directly by the bank and takes only a few seconds.
If authentication is confirmed, the transaction is authorized. Otherwise, the payment is declined.
In some situations, the bank may authorize the purchase without requesting additional authentication if it considers the information provided sufficient to validate the transaction.

How can authentication be done?

Validation can occur in different ways, depending on your card's issuing bank, such as.

  • Password or PIN
  • Code sent via SMS or bank app
  • Biometrics
  • Facial recognition

If you receive an authentication request during purchase, don't worry. The process is secure, intuitive, and similar to the confirmations you already use when accessing banking apps, emails, or social networks.

Important information

The Mundpay does not act in the environment where authentication is performed. The entire verification process is managed directly by your card's issuing bank, which defines the interface and authentication method used. That's why Mundpay has no control over the screens or information displayed during this stage.
