PCI DSS compliance is a critical security requirement for retailers
You must comply with PCI DSS requirements if your business is involved with handling credit card data from any of the major card brands (Visa, Mastercard, Discover, American Express and the JCB Card).
Failure to comply may subject you to fines, penalties and restriction of your bank card acceptance privileges. You can be sued, suffer reputational damage and lose business. You may also need to submit privacy breach reports to state authorities and provide identity theft coverage to your affected customers.
