What are Single-Use Virtual Cards?

Single-use virtual card numbers are the secret weapon against online fraud—and yet so many people don’t use them! Instead of giving your real card number to every website, these cards generate a new number for every purchase, automatically expiring after one transaction. That means zero risk of fraud! Why hasn’t anyone told you about this? Most folks still rely on their main card, leaving them vulnerable. In 2025, 48% of consumers started using AI to shop, but you can take control today. Sign up for services like Privacy.com or Capital One Eno, and start protecting your finances with virtual cards NOW!
