DigiYatra produces Biometric Enabled Seamless Travel (BEST) experiences based on facial recognition technology. History 

DigiYatra app was developed by Hyderabad-based startup Dataevolve Solutions. This startup company was selected through the national start-up challenge conducted by NITI Aayog under Atal Innovation Mission (AIM). DigiYatra was launched on 1 December 2022 by civil aviation minister Jyotiraditya Scindia in its first phase in Bangalore and Varanasi. In April 2023, the Digi Yatra service was expanded to Vijayawada, Kolkata, Hyderabad, and Pune airports. In June 2023, Delhi Airport’s Terminal 3 (T3), announced that passengers traveling from T3 can now benefit from the convenience of the Digi Yatra facility from the airport premises without requiring the DigiYatra mobile application. In the same month, the user registration on Digi Yatra mobile application crossed the 1 million milestone. See also
