How does the freedom of services work in the EU, and what are the different ways it can be applied across borders?

Freedom of Services: Active services: The provider travels to another country to offer a service. Passive services: The customer travels to receive a service. Combined: Both the provider and customer travel. Only the service: The service itself crosses the border (e.g., online services). These freedoms apply to EU and EEA (European Economic Area) countries.
