Mehta said the trial run of the software by the Delhi Police should start from February 20.Last week, the Unique Identification Authority of India (UIDAI) allowed face recognition as additional means of Aadhaar authentication to be used in combination with existing ways such as fingerprint or iris scan.The move will enable easy authentication for those individuals who face a difficulty in other biometric authentication like fingerprint and iris.The facility is being allowed only in a “fusion mode” that is along with other existing means of authentication, and will be available by July 1, 2018, an official release said.
