Every day, airlines worldwide welcome almost eleven million passengers. That’s four billion per year.
Only a few of them may be a security threat, but you cannot afford to miss a single one. This means border personnel need all the support that technology can provide.
Most countries have no effective systems for managing passenger data. This critically weakens their border security. The UN recognized the seriousness of the problem, and in 2018, made it mandatory to have an API system.
