How agents book their ticket, especially in case of trains from kerala to mas for migrant workers is. They will book one genuine traveler, who will be their staff and other 5 will be some random name. And in train, genuine person will show ID card, while other 5 will random people to whom they sold ticket. Now with enforcement of adhar card, they cant randomly give name.
But again it is not a big thing. They will get 5 adhar card details and use it for random booking. How they are implementing, we will have to wait and see. If adhaar check happens during booking time, then it will big blow during tatkal booking time. Already IRCTC is very slow, now...
more... if this check also happen. Then tatkal will become more hectic.
