Virtual Credit Cards
While virtual credit cards have been around for several years, many people are unfamiliar with them. Also known as a substitute credit card, a virtual credit card allows the user to generate a new number for each online transaction. Doing so makes it much more difficult for anyone to steal the number and use it without your permission, simply because each newly generated number is intended for a single use only.
To establish a virtual card, you must first submit an application to a provider that offers this type of program. If your credit card application is accepted, you are assigned a credit limit and given instructions to download software that allows you to generate the new number for each purchase. The software automatically ties the purchase back to your main account so that all of your purchases still appear on one easy-to-read monthly statement.
The single greatest advantage to virtual cards is the level of consumer protection they offer.
