Final answer:
While a Qualified Integrator/Reseller helps support PCI DSS compliance, it does not guarantee it. PCI DSS compliance is a continuous responsibility of the business.
Step-by-step explanation:
The use of a Qualified Integrator/Reseller (QIR) does not ensure PCI DSS compliance but rather supports it. While employing a QIR can enhance the security measures and compliance efforts, PCI DSS compliance is a continuous process that involves ongoing management and adherence to the requirements. Businesses must implement, maintain, and regularly update their security practices to achieve and maintain PCI DSS compliance. A QIR can help implement these practices correctly, but it is the responsibility of the business to ensure full compliance at all times.
