PCI DSS, the Payment Card Industry Data Security Standard, is a set of security requirements for any business that stores, processes or transmits payment card data. It was created by the major card brands and is maintained by the PCI Security Standards Council.
The standard covers areas such as building and maintaining secure networks, protecting stored cardholder data, using strong access controls, monitoring and testing systems regularly and keeping an information security policy. How much a merchant must do depends on how it handles cards, and merchants are usually asked to complete a self-assessment questionnaire through their payment provider or acquirer.
Retailers and venues reduce their burden by keeping card data away from their own systems. Using certified payment terminals and integrated payments means card details go straight to the payment provider rather than passing through the POS or being written down, which narrows what needs to be protected.
Common pitfalls include storing card numbers in spreadsheets or emails, using default passwords on devices, leaving the network flat so that the POS shares space with guest Wi-Fi, and ignoring software updates. Merchants should check their acquirer's current requirements and not assume compliance is a one-time task.
PCI DSS matters because a card data breach can bring fines, remediation costs and damage to customer trust. RetailCare supports secure payment setups and managed IT, including network segmentation and updates, which help businesses work towards compliant environments.
