The Payment Card Industry Data Security Standard is an information security standard for organizations that handle branded credit cards from the major card schemes. The PCI Standard is mandated by the card brands but administered by the Payment Card Industry Security Standards Council.
If the office uses RevPayments, your questions can be addressed by reaching out to Global Payments Customer Service. If the office uses some other form of payment processing, you will need to reach out to your credit card processor.
