What does SAQ-B indicate for merchants?

SAQ-B (Self-Assessment Questionnaire B) is specifically designed for merchants who process cardholder data only through standalone terminals that are not connected to the internet. This means that these merchants do not store cardholder data electronically nor do they use custom applications for processing payments.

The correct association with SAQ-B is that it pertains to merchants who utilize imprint machines or standalone dial-out terminals. This setup indicates a level of security that aligns with regulatory compliance, as these methods limit the risk of exposure to electronic cardholder data. Merchants using such terminals are only handling card data in a way that minimizes their technological vulnerability.

The other choices describe scenarios that do not align with the requirements of SAQ-B. The use of mobile payment applications or electronic cardholder data storage would imply a more complex operating environment that necessitates a different self-assessment questionnaire. Furthermore, having full control over cardholder data processing would extend beyond the simplified requirements laid out for those eligible for SAQ-B.
