AN ON-LINE poll by Huddersfield MP Barry Sheerman revealed the majority of those taking part were in favour of ID cards.
Those looking up his www. barrysheerman.labour.co.uk website were able to take part in the poll.
Mr Sheerman hailed the success of his first bid to use the internet to gather constituents' views.
Now he is launching another web survey - about smoking.
Mr Sheerman said: "I am pleased that so many people took part in my first on-line poll.
"The results show 61% of those who participated in the poll are in favour of the introduction of ID cards and 39% against.
"Although a majority were in favour, many people have reservations about the implications for civil liberties and the costs involved."
Mr Sheerman is now asking constituents to tell give views on whether smoking should be banned in public places.
He said: "I have been active in calling for a ban on smoking in public places to protect workers' health and I am keen to see how the people of Huddersfield feel about the issue."
Mr Sheerman added: "I hope to maintain a regular consultation on a range of issues.
"The success of the on-line poll shows that people are keen to contribute to the democratic process.
"I welcome the input of my constituents which helps me in my job of representing them in Parliament."
