At the core of PCI's Data Security Standards is the notion that businesses that accept credit and debit cards must be responsible for keeping that sensitive customer data secure. While a lot of this is the responsibility of your IT department, your boss, and the people who maintain and choose your POS devices, some of it does fall on you. As a POS operator, you will come in contact with sensitive customer data, and you must keep it secure. In this course, we'll talk about how to keep this information safe. We'll go through some PCI DSS-related terms you should be familiar with. We'll also talk about why this matters and how it impacts you directly.
