This extension allows you to prevent payment card numbers from being displayed and to get a notification that the page potentially contains such information. All detection is done in-browser and no information is sent to any other location.
It's useful for preventing accidental forwarding of emails with card numbers in online email systems. It can allow the identification, reorting and instigation of Incident Response where unexpected credit card or debit card numbers are located. See https://www.pcisecuritystandards.org/ for details of the PCI DSS standard.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
