Why do you need a credit card during free trial signup?  E-mail this product to a friend

To ensure that service is not interrupted at the end of the free trial period and to prevent abuse of our services, Incartia requires a valid credit card number during the free trial signup process.  Customers who choose to cancel during this period will not be billed for the Incartia Service unless they accrue overage fees for use of services in excess of those allotted with their account, or choose to purchase add-on services.
