What is a virtual credit card?

@liam 

A virtual credit card is a temporary and fictional credit card number that is generated for online transactions only. It is designed to enhance security and protect the user's actual credit card details from being exposed during online purchases. Virtual credit cards typically have a set expiration date and spending limit, and they cannot be physically used like a traditional plastic credit card. They are often offered by banks or financial institutions to provide an extra layer of protection for online transactions.
