I needed PCI compliant tool to process using Realex on my Magento site. I am based on CE of Magento and I needed saving credit cards. PCI compliance is a real pain in the arse especially when it comes down to storing credit cards of your customers. I am not a payment gateway and do not have resources to implement all the PCI stuff so I decided to use Xpay. It just works fine for me.
Thank you Alex and the team!
