This is such a useful feature to have for my Capital One cards. It gives me peace of mind when I shopping online. I have dealt with fraudulent transactions on a different credit card and it's such a headache. With Eno I don't have to worry as much because if someone get the card number I can just delete the virtual number without replacing my entire card and the headache of changing every auto payment. It has worked for me every time I have used it. I could see where the pop up might be bothersome if Capital One isn't your primary card but I don't mind just closing when it's not needed.

Love it. Gives me such peace of mind when I am purchasing things online.

Helps shopping become even simplier!

I see a lot of people having problems, but so far it's been working like a champ for me, even on my Mac. Super quick and easy compared to what I had been using with another card company.

Works great! If your card gets stolen from a website, it's isolated to that website, so it reduces the issue.

useful and works like a charm

Love this useful extension - now I can shop online and be certain that the merchant has only the assigned card, not shared. Works very well for creating unique card numbers.
