The volume of global air passenger traffic has grown dramatically in recent decades, already exceeding 4 billion passenger journeys in 2018. Since 9/11, Advance Passenger Information (API) and Passenger Name Records (PNR) have been vital to combatting passenger-based threats to civil aviation security. The introduction of smart matching of biographic data and greater use of biometrics means that passports and other travel document types may become a thing of the past.
The need for watertight border security is undeniable. Recognizing the seriousness of the need for better security, the UN made it mandatory in 2018 for countries to have an API (Advance Passenger Information) system in place.
