Being Payment Card Industry Data Security Standard (PCI DSS) compliant means that you meet all applicable requirements of the current PCI DSS on a continuous basis.
PCI DSS was created by major card networks to increase the safety of cardholder data and reduce the risk of fraud. All organizations that deal with payment card processing must be PCI-compliant, which means fulfilling very strict requirements on securing cardholder data.
Merchants who find it difficult or expensive to fully comply with PCI DSS requirements may consider using encrypted methods (such as client-side encryption) or outsourcing card processing to a PCI-compliant payment service provider, such as us. This way their PCI DSS-compliance scope can be significantly reduced.
