Credit Card Processing, Security and PCI Compliance

Discover Information Security and Compliance Program

by

If you process credit cards (whether face-to-face or online) you need to be fully compliant with the guidelines and regulations for credit card security and processing. In this article we’ll be exploring the Discover Information Security and Compliance (DISC) Program.

Before we get into Discover’s specific rules, you’ll need to make sure you’re compliant with PCI DSS – This is an agreed set of requirements for everyone involved in the credit card system. You can check out our article on PCI compliance if you need more information.

Meeting PCI DSS standards is essential, as that’s what Discover and other credit card providers will ask you to prove. Once you know you’re meeting PCI DSS, you can start going through Discover’s compliance program. Here’s how.


Find Out What Merchant Level

All of Discover’s requirements are based on what’s called your “merchant level” (from 1 to 4 – 1 being the highest), with higher levels needing to do more. You can find your merchant level as follows:

You’re a level 1 merchant if:

  • You process more than 6 million transactions annually on the Discover network.
  • Another credit card provider (e.g. Amex, Visa) has decided you are a level 1 merchant.
  • You have suffered a data security breach resulting in an actual or suspected compromise of Discover cardholder data.
  • Discover decides you’re level 1.

You’re a level 2 merchant if:

  • You process between 1 million and 6 million transactions annually on the Discover network.

You’re a level 3 merchant if:

  • You process between 20,000 and 1 million transactions annually where the cardholder is not present (e.g. online transactions).

You’re a level 4 merchant if:

  • None of the above conditions for other levels apply.

Once you know your merchant level, you can find out what requirements you need to meet.
