When you, as a retailer, start accepting credit and/or debit cards for payment using the QuickBooks POS Merchant Service, you have a responsibility to comply with the requirements of the Payment Card Industry Data Security Standard (PCI DSS).
PCI DSS includes requirements for the configuration, operation, and security of payment card transactions in your business, and extends beyond your use of Point of Sale. It includes requirements for restricting user access, as well as for protecting your computers, operating system, and network, and for communications with other computers and the Internet.
Intuit has prepared an electronic PCI DSS Implementation Guide to help you learn about and comply with these requirements. You can access this guide via the link below or at any time by selecting User Manuals from the Help menu (Adobe Acrobat Reader required).
