As someone who works with a POS machine, you'll be processing payments via credit or debit cards. The PCI Data Security Standard regulates many security features that these cards must have, so you should be familiar with and able to identify the different security features on a credit or debit card. In this course, we'll go over what these are and what they look like. We'll discuss the cards' front features including cardholder names, card numbers, expirations dates, and Smart Chips. We'll also discuss the back features of credit and debit cards, which include the signature panel, the Card Verification Value, or CVV, and the hologram.
