Having recently received the credit card bill for a card that has not been activated since I received it several months ago, I was surprised to find charges on the bill. Somehow I managed to use this unactivated card to sign up for a monthly MLM deal, purchase travel from hotwire and a train ticket as well. As I said, this card has been in my wallet with the little sticker to call this number from my home phone to activate it, for over seven months! But the charges didn’t start until November. How 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.

Just like using a disposable camera instead of your expensive camera while you are traveling to protect from loss or damage, you can use a virtual card to prevent loss when purchasing online. With a virtual credit card number, the number is discarded after one use.

Since credit card fraud is so widespread we aren’t surprised when it happens and the card companies are looking for ways to cut their losses. This must be done without inconveniencing the ability of their customers t make purchases either in person or online while protecting vital information. They are hoping that virtual card numbers will be the solution.

The use of virtual card numbers for online purchases work the same way as a normal card number except they are only valid for a short time period. These numbers are issued as a short term replacement of the actual card number and are only valid for a short period of time. True card information is not sent to the vendor and these numbers can be single use or they may be used for multiple purchases over a short time period before it is no longer valid.

The objective here is to protect the real number from those who would use your card for their purposes thereby damaging your credit. If a computer hacker accesses a secure processing center to gather card information having used a virtual number could save your credit. Their attempted use of the virtual number will lead to 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 biggest benefit is from protecting your valuable information online. If such a number is stolen, it is or becomes worthless in a short time. If you make several purchases with your credit card per month you may see a real benefit from using virtual card numbers to assure all your transactions are secure and your information protected.
