In order to improve the security of customer data, the credit card companies have come together to create a security standard, called Payment Card Industry Data Security Standard (PCI DSS), which involve mandatory requirements for merchants that accept credit card transactions. All restaurants that accept a credit card must comply with PCI DSS. The purpose of the study was to examine the PCI DSS compliance levels of Quick Service, Casual/Family and Fine Dining restaurants. A random sample of 1000 restaurant managers that are in charge of information technology at their companies and are subscribers of Hospitality Technology Magazine were surveyed. One hundred ninety managers responded to the survey. The results indicate that restaurants are far from full compliance with PCI DSS. This may have significant financial and non-financial consequences for restaurant owners and operators.
