Digi Yatra's service enables contactless, seamless check-in of passengers at the Delhi Airport and Bengaluru's Kempegowda International Airport at all checkpoints; a beta version of Digi Yatra will handle passenger entrance based on the facial recognition system.

Facial recognition is a method of identifying or confirming a person's identity based on their face. Facial recognition systems can identify people in photographs, videos, or real time.

Facial recognition is a category of biometric security. Other forms of biometric software include voice recognition, fingerprint recognition, and retina or iris recognition of the eye. The technology is used primarily for security and law enforcement purposes, although interest in other application areas is growing.

Delhi International Airport Limited (DIAL) recently announced the launch of the app's beta version. All domestic passengers with Android devices will be able to use the service at all airport checkpoints.

At all checkpoints, such as airport entrance, security checks, airline boarding, etc., using this technology, travelers' entries will be automatically processed based on the face recognition system. Furthermore, the BIAL claims that the data will be deleted 24 hours after the completed trip.

The face recognition system complies with industry ISO standards. In addition, it uses top-tier algorithms from the National Institute of Standards and Technology (NIST), which are designated as meeting the government's requirements for data privacy and protection.

In addition to airports, security check areas, and aircraft boarding, the facial recognition system will automatically enter passengers. The traveler must link their Aadhar information, snap a selfie, and include the COVID-19 vaccination information and advised instructions to register.

The app provides a decentralized mobile wallet-based identity management platform to speed up airport check-in. A digital wallet will be provided to passengers, allowing them to store their credentials and other travel-related documents. The wallet will be encrypted, according to authorities. 

In 2019, DYF was established as a joint venture between the Airports Authority of India (AAI) and airports, including BIAL, DIAL, GMR Hyderabad International Airport Limited, Mumbai International Airport Limited, and Cochin International Airport Limited.
