New Technology Helping Prevent Credit Card Fraud Online

Virtual card numbers from Eno® are the proactive way to shop safely online


Data breaches are an unfortunate reality in today’s highly connected world. It’s a lucrative industry and hackers have plenty to gain—billions of dollars a year, in fact. So what can consumers do to minimize their risk—and reduce the impact and disruption a breach can cause?

Being proactive has always been our best bet. We beef up our passwords, get more tech-savvy, spot suspicious emails, and practice safer browsing with encrypted connections. That covers the before and during of online safety, but now there’s a way to keep your card number safe in the wake of a breach, thanks to innovative virtual card number technology from Eno, the Capital One® assistant.

Eno and virtual card numbers help protect you in the event of a breach when a merchant’s been compromised. The unique technology helps make online shopping safer and can upgrade your security in a whole new way.

Virtual credit card numbers: more peace of mind in the event of a breach

Any security-savvy consumer knows the minute you hand over your card number, you’re putting your trust in that merchant to keep it safe. Before now, there was no way around providing your card information to complete a transaction, but Eno bypasses that risk by taking your card’s actual number out of the equation entirely.

Here’s how it works: Eno is installed as a browser extension and at checkout, will pop up and create a unique, merchant-specific card number for that site. Eno auto-fills the number for you, then you continue the checkout process as usual. Each virtual number gets stored in a dashboard you can access and manage—which is where the other major security benefit comes in.

Taking action with Eno after a breach

Say a merchant you’ve shopped with is compromised. In the past, that meant changing your card’s number or closing your account, which can be pretty disruptive if that’s your primary card. With Eno’s virtual card numbers, you’re not helpless after a breach. Instead, Eno users can simply lock or delete their virtual number associated with that merchant. Even if hackers did get their hands on the virtual number, the damage stops there and your normal spend elsewhere isn’t interrupted.

Make privacy a priority

Of course, staying vigilant online will always be important. While virtual card numbers can offer that extra peace of mind, the best way to avoid fraud is with a holistic approach to security. Stay security savvy with this helpful checklist of ways to protect yourself online at every step, from browsing to checkout.

Security-Savvy Shopping Checklist

1. Use a password manager

Using the same password across multiple sites? A password manager can create and store hard-to-crack passwords for all your sites.

2. Brush up on your suspicious email spotting

As a rule, don’t click links in emails that ask you to log in elsewhere. Log on to a site directly if an email sounds urgent, threatening, or if you notice obvious typos in the text.

3. Scan devices for malicious software

Ensure no one’s monitoring activity on your device by running programs designed to detect hidden malware.

4. Keep an eye on the URL bar

Look for a padlock symbol or “https://” to know you’re browsing over an encrypted connection.

5. Implement 2-factor authentication for logins where you can

Enabling this verification process on important accounts. It sends a login code via text, which makes it so only someone with physical access to your device can log in as you.

6. Limit your online activity on public WiFi networks

Hackers use devices set up convincing-looking phony networks in public places. Once you access their network, they can monitor all your activity.

7. Only shop online over secure networks

Hackers are good at eavesdropping; lock down your connections before you share any financial data over the web.

8. Only pay through verified payment options

Online stores are required to meet certain standards for security. If a site’s checkout seems shady or isn’t verified, listen to your gut.

9. Install the Eno browser extension

Pay with virtual card numbers everywhere you shop.

10. Make sure your credit card issuer offers fraud detection

For example, if you’re a Capital One customer, you’ll receive a proactive alert from Eno if any unusual activity is detected.
