A Virtual credit card works in a similar fashion to the physical form. It has its own card number, CVV, and expiry date. However, it does not come in a physical form. It only exists online and is typically accessed through a smartphone or bank app. These cards are safeguarded by a passcode or biometric login, making them harder to misuse. Most importantly, the card details are generated uniquely for each transaction or for a limited time, which helps reduce the chances of fraud. If any suspicious activity occurs, the card can be instantly blocked without affecting the main credit card account.
