Assembly Elections

Do the Election authorities verify the identification proof of the voters?

I went early in the morning and took my passport as I did not have my voters id. In the polling station, there was one Presiding Officer to supervise the proceedings. Then one Polling Officer, was reading out my voter number and name loudly so that the observers from the political parties can note down.

There was another Polling Officer, who applied(rather I should say poured) the indelible ink. Then there was one who wrote a couple of serial numbers in a piece of paper and passed it to the Officer sitting next to her, and he got a signature from me.

At last there was one Polling Officer with a gadget, instructing people to press the blue button opposite to the candidate of their choice. No one bothered to ask for my identification proof. Is this the case everywhere or was it in my polling station only?
