Who has to be PCI Compliant

In case you are a merchant that is accepting credit card payments online, your acquirer contractually requires you to comply with PCI DSS. Based on how the collection of payment data is handled in your online store, it can result in costly and time-intensive reviews that have to be done including massive investments in your security infrastructure.

What Assessment Type is Necessary

All wallee.com users that process credit card payments have to be compliant with the PCI Data Security Standards (PCI DSS). The payment page and the iframe integration meet all the requirements and security constraints of the Self-Assessment Questionnaire (SAQ - A), by performing all transmission of sensitive cardholder data within the payment page or iframe served off of a wallee.com domain that is controlled by wallee.

All data wallee returns in the responses or webhooks is non-sensitive card information in the response to a charge request. This can includes the cardholder name, card type, the last four digits of the card, truncated card data and the expiration date. This information is not subject to PCI compliance, so you are able to store any of these properties in your database. However, this data is most likely subject to your country's data privacy law and in case you store it, make sure it is secured accordingly.

Proof of Compliance

It is ultimately up to your merchant / acquiring bank what they ask you to provide to prove your PCI compliance. However, if you are using wallee.com you will rely on our PCI certification and complete the Self-Assessment Questionnaire (SAQ - A).
