After Bengaluru Airport, Hyderabad is the second city in the country to embrace facial recognition technology for paperless boarding. This mechanism has already been tested and is said to be implemented by year-end, according to The News Minute. Using 3-D cameras that will be set-up at three checkpoints, you'll be able to sail through the security gates without presenting your documents or identity proofs. This technology is the first-of-its-kind in the country and Hyderabad is the first city to get it. Wuhoo! While as a first step, the travellers have to enroll themselves and get their data registered, they can walk past the gates with no fuss, after that. Easy-peasy!
