For homeowners who have a Sky TV subscription, a Sky card is needed to access the programming the service provides. A Sky card is used with the digibox so that users can enjoy up to more than 200 English-speaking channels around the world and get high quality entertainment in digital and high-definition television format. Having a Sky Viewing card gives the users access to a variety of top channels on Sky HD like Sky Movies HD, Sky Documentaries HD, Sky Sports HD and SKY Entertainment HD. Users who have an active subscription to the complete Sky World package and also subscribe to Sky 3D are given full access to premium 3D channels including Sky Movies 3D, Sky Sports 3D and Sky Documentaries 3D. Sky Viewing cards are also needed by Sky TV subscribers from outside the United Kingdom, including those residing in Europe, Asia and North Africa. In addition to giving users complete access to Sky channels, users can also utilise the Sky card when they need to get Sky TV channels on another television. Homeowners can order Sky cards with a new digibox or just simply order the Sky cards if they already have an existing digibox.
