What is PCI and why it is important?

Any organization involved with the processing, transmission, or storage of card data must comply with the Payment Card Industry Data Security Standards (PCI DSS).

Checkout Technology Ltd, a company within the group, is certified for PCI DSS as a Level 1 Service Provider, which is the highest standard set by the payment card industry to ensure that credit card data is processed, stored or transmitted in a secure environment.

Who is responsible for PCI DSS compliance?

What are the requirements?

There are four levels of PCI compliance that merchants are organized under, based upon their card transaction count over a 12-month period. The PCI level in combination with the integration method will determine the compliance requirements for each merchant.
