Card tokenization

When contracting the tokenization service (Cartão Protegido), you can securely save a credit card in compliance with PCI DSS standards.

Card data is stored as a token (excluding the card’s CVV), which simplifies sending and processing transactions, ensures the integrity of stored cards, and replaces their data in future transactions for the same shopper.

In addition to creating the token (CardToken), you can associate a nickname (a text identifier) with the saved card. This identifier will be the Alias.

⚠️

Use cards that follow the Luhn Algorithm

For security reasons, Cartão Protegido only accepts saving cards that pass the Luhn Algorithm check, also known as "mod10".

Credit card transaction flow with tokenization

In a transaction using Cartão Protegido, the card tokenization request is made within the authorization request itself.
