Hi All, Mews Payments is a PCI DSS compliant platform and for the reason of making sure that guest personal information as card details are not exposed the the fraudsters or any card leakage we ensure that our platform doesn't expose any card details to not only to you - our customers, but also to us, Mews team. We only have access to tokenized cards, same as any property. On this way your property and your guests are kept safe and protected against fraudsters. Everyone can see last four digits of the card details - which is a secure and enough of a way to detect the card, alongside the information about its format, cardholder name etc. This is something that Mews will never allow due to high quality standards we hold ourselves to, however, if any additional data can be added to Mews that will help you operate better and detect e.g. ownership of cards, I am happy to hear your feedback. Thanks for the idea!
