IRCTC has changed the rules for Proof of Identify for e-tickets.
Now it is not necessary to specify the person and the ID details. Any one of the passengers need to carry one of the specified proof of identity (Voter ID card/ Passport/PAN Card/Driving License/Photo Identity Card) along with the Electronic Reservation Slip (ERS).
Earlier it was necessary that one passenger (as specified during booking) to carry the pre-specified Identity proof. It was cumbersome esp. if we forget to take THAT particular Identity Proof or that passenger needs to cancel the ticket.
It would be great if the Ticket Examiner also does not insist on ORIGINAL Driving License when even the RTO Inspectors and Traffic Police allow Laminated Colour Photocopy as valid Documents to be carried instead of the original.
