I just received my the credit card bill for a credit card I haven’t even activated since receiving it several months ago. It appears I have signed up for some monthly MLM deal as well as purchasing a train ticket in Washington DC. Oh, and I also bought something from hotwire.com. Now, as I say, the card has been in my wallet since I received it seven months ago and still has the little sticker on it telling me to call and activate it from my home phone. The charges only started in November. Could this have been prevented?

Throw away card numbers – virtual card numbers – can be of some use when shopping online but I doubt they would have prevented what happened to me. In my case, the thief had somehow determined my name and correct card information. If you want to use virtual card numbers for online shopping protection that is fine, just don’t be lulled into a false sense of security. They wouldn’t have protected me since I wasn’t even using the card to make physical purchases.

Similar to using a disposable camera while traveling to protect your expensive one from loss or damage, a virtual card can prevent loss when used for online purchases. In this case, it is the number that can be used once and then discarded.

With widespread credit card fraud nobody is surprised when it happens and the credit card companies are constantly looking for a way to prevent losses due to fraud. The method must not inconvenience their customer when it comes to using the account for purchases either online or on person yet it must also protect consumer information. Their hope is that virtual card numbers can solve this problem for them and their customers.

While virtual cards are used to purchase online in the same manner regular cards are, they are temporary numbers. These numbers are issued as a short term replacement of you true card number for purchases. Your personal information is not transmitted to the vendor and often they are single use numbers and a new number must be generated for subsequent transactions. There are other cases where a virtual number can be used for multiple purchases over a limited time period before it cancels.

Virtual card numbers are intended to hide the real number from those who wish to use your information for their purposes and possibly damaging your credit. Should a secure processing center be hacked by someone wanting credit card information, your use of a virtual number would render your account safe. If they used your virtual number the result would be a denial of credit.

You expect that your card information is safe and secure at secure sites during your purchase. There is however the possibility that an employee of an online merchant could sell credit card information to criminals. While this in itself is a criminal act some people are willing to do anything if the payoff is high enough and there is little chance of them being caught.

Virtual credit card numbers protect your valuable information during online purchases. If a virtual number is stolen it is worthless or becomes worthless in a very short period. When making several purchases with your credit card a month you may realize a real benefit from using a virtual card number for protection and security.
