Self-Assessment Questionnaire B is probably the most popular of all the SAQ types provided by the PCI SSC. SAQ B applies to the majority of small business retail stores. SAQ B applies to the most basic and traditional methods of processing credit card payments. It basically addresses the simplest processing methods, from old style card imprint machines to the basic telephone dial-up card terminals. With only a few more requirements over what is needed for SAQ A, SAQ B is a simple and straight forward questionnaire for reporting your PCI compliance.
