In today’s world, an ever-increasing number of purchases and payments are being made by credit card. Although merchants and service providers who accept credit cards have an obligation to protect customers’ sensitive information, the software solutions they use may not support “best practices” for securing credit card information. To help combat this issue, a security standard for credit card information has been developed and is being widely adopted.The Payment Card Industry (PCI) Data Security Standard (DSS) is a set of guidelines for securely handling credit card information. Among its provisions are recommendations for storing customer information in a database. This paper will outline how software vendors can take advantage of the InterSystems Caché® database – now and in the future – to comply with data storage guidelines within the PCI DSS.
