If you shop online or subscribe to any service, you might want to use a pre paid credit card. With a regular credit card if you pay for a service and then want to stop you might still be billed for months before they company stops charging you. If you use a pre paid card then you would be in control. The company going into your account would only be able to get the funds that you had in the account. If for example you only had $20.00 and they tried to get any money you would only be out $20.00 with a regular credit card they can keep going until they reach your limit. When I shop at site that I am not to sure about I like to use the pre paid card at least I know that I will have my main credit card number stolen. With time we will see more people using a pre paid card for shopping online and a regular credit card for the real world and to shop on only trusted sites.
