When using Authorize.Net payment method, what happens to credit card numbers?

When using the Authorize.Net payment method in a Magento setup, credit card numbers are not stored directly in the database for security and compliance reasons. Instead, they are saved as tokens with the order.

This tokenization process means that sensitive credit card information is replaced with a unique identifier or token that can be used for processing payments without exposing the actual card number. This is particularly important for maintaining PCI compliance, as it significantly reduces the risks associated with storing sensitive credit card data. The token allows for future transactions or billing processes to happen securely without needing to re-enter the card information.

By using this method, Magento enhances security for both the merchant and the customer, allowing for convenient transaction handling without the risks tied to storing actual credit card numbers.
