phor to specify a service. A card is typically a unit 
of interaction with the user, that is, either presenta-
tion of information or request for information from

HTML, WML is designed to fit small handheld 
devices.
WMLScript
WMLScript can be used to enhance the functional-

may be utilized in HTML. It makes it possible to 
add procedural logic and computational functions 
to WAP-based services.
