The main purpose an individual or company would want to use a throw away card offer number is for shopping online. Many people still fear shopping on the Internet. The concern is that hackers will get a hold of their number. However, these days, there are many secure websites that use SSL technology to encrypt Reloadable vcc transactions being made online. Large online retailers such as Amazon and Wal Mart spend large amounts of money every year on online security measures that will protect their customers. Consumers should also be aware that most issuers have a zero fraud liability policy that protects their customers against theft. However, for those that are still skeptical about making purchases online you can always request a temp card number from your issuer.
There are quite a few disadvantages to using a temp or throw away number. When you go to rent a car online for example, you give them a one time use card number and they will only be able to verify it once. At the end of the car rental the rental agency will need to total your millage costs, fuel costs, etc and re charge your credit card. If you give them a disposable card number that can only be used once they will not be able to finalize your charges. The same hold true when you use your card to make hotel reservations or even buy theater tickets online. The other major disadvantage to using these numbers is when you need to make recurring payments online. For example you could be purchasing vitamins online that have refills sent to you every thirty days. Your online vitamin retailer will not be able to charge your card multiple times if the number is going to expire immediately.
