PCI Compliance
CartIt 8.0 should be able to be used in a PCI compliant manner when used with a PCI Compliant third party payment processor. Manual Credit Card payment in CartIt is not presently PCI Compliant and should be used for testing purposes only. This site was brought online to further develop CartIt with the goal of making manual payment processing PCI compliant.
The PCI compliance requirements encompass more than just the shopping cart- you should apply this standard as a minimum level of security for your e-commerce business.
