PCI DSS

The Payment Card Industry Data Security Standard — the card schemes’ rules for handling cardholder data. What a merchant has to do under it depends mostly on whether card data ever touches their own systems: a shop using a supplied terminal, or a website using a hosted checkout page, carries far less of it than one that captures card numbers itself.

Why it matters to a merchant

The standard is far smaller for most merchants than the name suggests, and the reason is scope: what applies depends on how much cardholder data the merchant touches. A shop taking payment on a terminal it does not own, and never storing a card number, is in a different world from one storing card data in its own system. Establishing which one you are is the first step and it usually shortens the list.
