Reading this :
as soon as the 'registered passenger' reaches the e-gates, he/she will scan his/her boarding pass issued by the airlines at the e-gates to get the details of his/her flight. The passport will also be scanned and biometric of the passenger will be authenticated at the e-gates. Once the genuine identity of the passenger is established and biometric authentication is done, the e-gate will open automatically and immigration clearance will be deemed to have been granted.
Once approved, do I just walk up to an e-gate (e.g. does BLR T-2 have one?), swipe my boarding pass, my passport, biometrics and clear immigration?
Is this actually operational? Is it able to handle the volume of pax flowing through T-2?
