Here is what they are, how they work, and why they matter more than ever in 2026.   Every time you log into a website using your Google account, check a flight price, or open a food delivery app and watch your rider move across the map in real time, an API is doing the work behind the scenes.

It involves a Japan based AI and biometric authentication company that already had a working facial recognition platform , used across smart buildings , retail , and security . Their...
