Who the PCI DSS applies to
The PCI DSS applies to any organisation that stores, processes or transmits cardholder data, regardless of size or transaction volume. This includes:
- Merchants (online and in-person)
- Service providers handling cardholder data on behalf of others
- Payment processors
Compliance Requirements
Organisations must comply with 12 high-level requirements, grouped into six control objectives. Exact compliance obligations vary based on the organisation’s merchant level, which is defined by the number of transactions processed annually and the associated risk.
