Thanks for all replies
well, some months back my friend happened to travel on motorway, he fiddled with the card and made it unreadable, same thing happened with him.
Though i am not of his kind (btw sab log akhar main yehi kehtay hain ), but my point is either quality of these cards is not upto the mark, or they themselves are providing us with a loop hole so as to cross speed barrier on road, then damage their card and exit smoothly. this is what pinches me.
any comments?
