Does this module support recurring billing?

Yes, it is fully compatible with WooCommerce Subscriptions. Cardinity can enable recurring payments for subscriptions or memberships. Cardinity uses the tokenization method. The system encrypts the data and creates a payment reference ID which is later used for recurring billing on a periodic basis.

Cardinity conducts regular checks to identify potentially fraudulent activities. We advise every merchant to activate the 3D Secure authentication tool. We enable it for free. Most importantly, Cardinity is fully compliant with PCI DSS standards.
