PCI DSS
Category: Payments
Also searched as: Payment Card Industry Data Security Standard
Definition (plain English)
The Payment Card Industry Data Security Standard for protecting cardholder data and reducing card-payment security risk.
Why it matters commercially
PCI scope affects checkout architecture, vendor selection, data storage, audit burden, and breach exposure.
Example
A retailer used hosted payment fields so card data stayed with the PSP and internal systems avoided storing sensitive card details.
Common mistake
Assuming a payment gateway alone removes every PCI obligation while still storing card data, logs, screenshots, or manual order forms.
