The ICAToll interface is supported by tolls. A toll represents a way to purchase or access a service. Every toll provides a way to �pay� the toll. This could be an actual monetary payment, or it could be some other action, such as entering a password. For example, parental policies might use a password toll. To pay a toll, call the ICAToll::PayToll method.
A toll can apply to a denial or an offer. Paying a toll on a denial removes that denial, while paying a toll on an offer purchases the offer. A toll can be blocked by one or more denials; if so, the user cannot pay the toll until he or she has resolved those denials.
In addition to the methods inherited from IUnknown, the ICAToll interface exposes the following methods.

| get_Description | Retrieves a description of the toll. |
