Available in the US, Canada, UK, Europe and many other countries, NetBanx (Optimal Payments) integration enables you to process all major credit and debit cards including Visa, MasterCard, AMEX, Discover, JCB and Carta Si.
The payment page is hosted by NetBanx, which means that you do not even touch the credit card info, thus the PCI DSS regulations are not applicable to your store at all.
