n. (plural of e-border English)
Wikipedia
e-Borders was an advanced passenger information programme which aimed to collect and store information on passengers and crew entering and leaving the United Kingdom. Passengers details were to be checked against terror and criminal watch lists before being stored on the e-borders database. Due to European law on free movement EU carriers and ports supply information to the UK Border Agency on a voluntary basis, however in March 2012 Damian Green said that by April e-Borders would be collecting information an all passengers on 100% of non-EEA flights to the UK. The information of the passengers and crew was to be collected by the airline, train operating company, ferry and other carriers and ports and is then passed on to the e-Borders programme via the Carrier Gateway provided by Serco. In 2014 it was announced that the system would be scrapped.
