E tickets are freely printable on our stationery, on our printer and in as many copies as you may be wishing to have. It can be fax or email copied too. This is the only reason that an Identity proof is required to verify whether the person(s) who produces on demand, is the genuine holder of the ticket.
We need not only to be concerned with the TTE in the reserved coach. It may be checked / required on the Platforms as well as on Exits of the Stations.
The provision...
more... seems all right.
Though not fully relevant but please be informed that in case of doubt, ID is demanded even on PRS TICKETS to be satisfied or to detect an irregularity. Since concession costs to the Railways, ID is required to be pocketed by Senior Citizens also as no proof is verified by booking the ticket.
Thanks !
