PCI-DSS affects which type of companies?

• A. E-commerce firms
• B. Medical firms
• C. Government organizations
• D. Companies that accept credit card payments

Answer: (D)

PCI-DSS governs how cardholder data is protected for any organization that processes, stores, or transmits credit card information. The key idea is that the security requirements apply wherever card data flows within the payment ecosystem. Therefore, the group most at risk of needing to meet PCI-DSS are the companies that accept credit card payments, whether in a store, online, or by phone, and the service providers that handle card data on their behalf.

Other sectors like medical firms or government organizations aren’t automatically in scope unless they actually handle credit card data. If they do accept card payments, they must meet PCI-DSS just like any merchant. In short, PCI-DSS affects those who handle card payments, ensuring card data is safeguarded across processing, storage, and transmission.
