KEEP YOUR CREDIT CARD NUMBER TO YOURSELF Eno appears at checkout and provides a unique virtual card number only for that site, allowing you to shop online without exposing your actual credit card number.

STEER CLEAR OF UNWANTED CHARGES Enjoy greater control over your online shopping experience. With Eno, you can lock or unlock your virtual card numbers anytime without affecting your other spending.

SET IT AND FORGET IT Virtual card numbers keep working even if you get a new credit card, so you won't need to manually update your card information on the sites where you've stored one. Eno will handle it behind the scenes, automatically.

CHECK OUT EFFORTLESSLY AND KEEP EARNING REWARDS Each purchase made with a virtual card number will be linked to your actual credit card account, so you’ll still earn the same benefits and rewards. To get started, add Eno to Firefox (it's free), and just click the Eno icon when you're ready to pay.

Eno is only available for Capital One cardholders. Not a customer yet? Click here to apply for one of our credit cards.
