The DBT Face Recognition System plays a pivotal role in expediting migration control in a cost-effective manner. Here's how it works: Before the trip, entitled travelers register in the DBT System, providing passport photos, flight booking details, and other necessary information. This data is processed by authorities using predefined protocols, generating a unique token ID registered on the traveler's smartphone. Upon arrival at the border control, the DBT automatic border control beacon detects the traveler's DBT smartphone.
