Detailed information about tokenization can be found here: Tokenization and Re-Use of Saved Credit Cards (X-Payments 2.x and later)

In general, the key features are:

• The credit card information itself is not stored in any way (neither in X-Payments, nor in the connected shopping cart).
• X-Payments stores a tokenized credit card internally. This is gateway-specific information, and, in some cases, it is not available to the connected shopping cart.
• The connected shopping cart can execute payment by token using txnId - a unique ID of the original payment which was processed using the real credit card details.

To be able to execute such a request, the following conditions must be met:

• The payment gateway supports the tokenization feature.
• Tokenization is enabled in the payment configuration in X-Payments (provided that there is such a setting). For example, this is true for Authorize.Net, NetBilling, Beanstream, etc.
• The buyer has chosen to save their credit card at checkout, or the card has been saved automatically for subscription/recurring payments.
