Context: From March 2022, passengers will be able to use a face scan as their boarding pass at four airports in the country.
Airports at Varanasi, Pune, Kolkata and Vijaywada will be the first to roll-out the facial recognition technology-based biometric boarding system.
Like all biometrics solutions, facial recognition technology measures and matches the unique characteristics for the purposes of identification or authentication.
Often leveraging a digital or connected camera, facial recognition software can detect faces in images, quantify their features, and then match them against stored templates in a database.
The Airports Authority of India has engaged NEC Corporation Private Limited for implementing the technology as part of the DigiYatra policy, which seeks to promote paperless air travel and a seamless journey from entering an airport till boarding a plane.
