The European Union has entered into negotiations on a new passenger data transfer agreement with the United States. It aims to reduce the number of personal details that people must provide to the US authorities when travelling to airports in the United States. The EU also wants to end the practice under which US authorities can freely access information from airline computers. Currently under US law 34 types of data, including credit card and passport details, e-mail addresses and travel itinerary, can be accessed by the US Department of Homeland Security and shared with other law enforcement agencies. According to EU Commissioner Franco Frattini, only 19 types of data need to be handed over. In addition, the EU would like to ensure that the data is transmitted to US customs only when they make a request for it.
