PCI Compliance Levels for Merchants & Service Providers.

The Payment Card Industry Data Security Standard (PCI DSS) outlines a set of requirements to help merchants secure payment card data against data breaches and card fraud. But, the requirements may not necessarily apply to all merchants equally. The PCI merchant levels mandated by card brands like Visa and MasterCard help determine the level of risk exposure and ascertain the appropriate level of security for protecting card data.
