PCI DSS – What Is It?

PCI Security Standards are technical and operational requirements set by the PCI Security Standards Council (PCI SSC) to protect cardholder data. The standards apply to all entities that store, process or transmit cardholder data – with requirements for software developers and manufacturers of applications and devices used in those transactions.

The Council is responsible for managing the security standards, while compliance with the PCI set of standards is enforced by the founding members of the Council: American Express, Discover Financial Services, JCB, MasterCard and Visa Inc. Read more about the PCI Security Standards below.


Attestation Of Compliance (AOC)

An Attestation Of Compliance, also known as AOC, is a form used by merchants and service providers, eg. payment service providers, to showcase the results of a PCI DSS assessment and thereby prove their security standard.

Our current compliance document for PCI DSS 3.2 is issued by Integrity.
You can find it below:


Pretty Good Privacy (PGP) is a versatile and widely-used data encryption infrastructure that plays a crucial role in ensuring secure communication and protecting sensitive information. It is particularly valuable in the context of online payments, where robust security measures are essential.

PGP utilizes advanced encryption techniques to safeguard financial data during transactions. By encrypting payment details, such as credit card numbers and banking information, PGP helps prevent unauthorized access and fraud. Integrating PGP into payment systems enhances security and instills trust in customers.

To communicate securely with us, Billwerk+, we encourage the use of our PGP key. If you’re unfamiliar with PGP, you can explore GPG, an open-source implementation of the PGP standard. GPG provides a free and accessible solution for implementing secure communication and payment protocols.
