Virtual credit card is provided by the issuer of your credit card that can be used exactly once to make a purchase. You use it like you would use a number of regular credit cards for an online purchase, by phone, or even on paper and your signature. The advantage of a virtual card number is that it can be used only once, and so that, it can protect your credit and your credit score. After using the number to purchase a product or service, it is no longer valid, so even if we get the number it is worthless to them and they can not make a purchase with it.
