If you are using Stripe.com (recommended) or Authorize.net, you can store the guest’s credit card details for later processing. The card can later be charged once or several times from the booking details page in Sirvoy.
The credit card details are handled and stored (or vaulted) by the payment provider. This is often called tokenization, since a less sensitive token is created to represent the actual card details. This means that no credit card details will ever touch your website, web server or computer. Neither will any card information be stored in Sirvoy. In other words, the card information will always be stored in a secure and PCI compliant manner.
