All merchants, whether small or large, need to be PCI compliant. The payment brands have collectively adopted PCI DSS as the requirement for organizations that process, store or transmit payment cardholder data. PCI SSC is responsible for managing the security standards while each individual payment brand is responsible for managing and enforcing compliance to these standards.
For questions regarding compliance validation requirements and deadlines as well as compliancePCI DSS is intended for all entities involved in payment processing, including merchants, regardless of their size or transaction volume. When compared with larger merchants, small merchants often have simpler environments, with limited amounts of cardholder data and fewer systems that need protecting, which can help reduce their PCI DSS compliance effort. Whether a small merchant is required to validate compliance is determined by the individual payment brands. For questions regarding compliance validation and reporting requirements, we recommend that youmerchants should contact yourtheir acquirer .
