Answer:
The areas that all airports are divided to ensure the safety of customers are called Initial checkup, Identity Checkup, Boarding Check up.
Step-by-step explanation:
The Initial checkup is done as soon as the customer arrives at the airport. At that moment, the customer and the baggage he or she carries go through a sort of sorting and analysis. At that moment, they are checked if the customer or the baggage has any prohibited elements or items.
Identity Checkup happens right after that, where the client undergoes a criminal check, in addition to presenting their travel destination. This phase is carried out to avoid possible criminal acts.
The last step is the Boarding Check up and it happens when the customer is ready to get on the plane. On that occasion the luggage is checked again, as well as possible documents.
