A virtual credit card is a temporary, randomly generated card number linked to your real bank account or credit card — but without a physical card. You get a card number, CVV, and expiry date that you can use for online payments, while your actual card details stay hidden.
How they work
When you generate a VCC, your bank or provider creates a unique card number on the spot. You use that number at checkout like any normal card. The charge routes through to your real account, but the merchant never sees your actual card details. Once the VCC expires or hits its spending limit, it becomes useless — even if someone intercepts it.
Why people use them
The main appeal is control. You can set a spending cap so a merchant can never charge more than you allow. You can create single-use cards for free trials, so the subscription never kicks in after the trial ends. You can lock a card to a specific merchant, meaning it'll only work there and nowhere else. And if a data breach exposes the VCC number, there's nothing useful to steal.
The drawbacks
VCCs are built for online use. Hotels, car rentals, and other businesses that need to verify your card in person often require the physical card — a VCC won't cut it. Refunds can also be tricky: if the VCC has already expired or been deleted by the time a refund is issued, getting your money back requires extra steps with your bank. Not all banks offer VCCs either, and managing them requires using an app or web portal.
Who offers them
In the US, Privacy.com is a popular dedicated service. Capital One offers a feature called Eno. Citi has its own virtual card tool. Internationally, Revolut and several neobanks provide similar functionality. Availability varies significantly by country and institution.
VCCs are a simple, practical layer of protection for anyone who shops online regularly — especially useful for managing subscriptions and protecting against card fraud.
