Yes, PayFast is PCI DSS Level 1 Service Provider which is the highest level possible.
But perhaps we should explain what PCI Compliance is:
PCI DSS stands for Payment Card Industry Data Security Standard and is a PASA (Payment Association of South Africa) regulation in South Africa, this means any company accepting credit card payments on their website needs to comply in some way. When you accept card payments on your website, you need to make sure you process cardholder data in a secure environment and this is where PCI compliance comes in.
Luckily because PayFast is PCI Compliant you don't have to be, so rest assured all your customer's credit card payments are done in our secure environment.
