No to ID - but yes to all other cards?

I am finally in my third year and i have to write my dissertation! Help!
I am witting about the ID card in Modern Britain. I am trying to understand why some people might be against the ID card.

If you wanna help me, then please answer the following questions.
I will use this in my dissertation however I will not use your name. Thanks a lot!

Are you against the ID card?
Please explain your answer.
Do you own any loyalty cards (ie: Nectar cards, Tesco club card, Waterstones card etc...)?
Do you own an Oyster card? If so, is it the one your registered for (ie: it has your photo on it)?
Do you own a passport and/or drivers license?
How do you feel about the government loosing people's information?
How do you feel about another network (not the government) having your information in their database?

Thanks a lot!
Hope you can help me out

I just want to thank all the people who reply to my post.
I have only had this blog for about 1 hour and already I got 3 posted comments.
May I just add that I will be using these comments in my dissertation and if you are not comfortable with that, please let me know.
I will not be using your name or username, I will make up a name!

Thanks again for your help!

The Nectar card, along with any other loyalty card, in indeed optional.
But for financial reasons, we choose to use them because we gain points which we can then exchange for goods.
Yet these cards are used to see who buys what in order for them to stock up their shelves to make profit.

This is what an ID card in the UK would look like. The information about the person is minimal compared to the information kept on other cards.
All the information here is information that any person would normally give out in a daily basis. Without it, one could not fill in forms and others such things.

This is an imagine I found near London Bridge by the Thames.
I have no idea who made it but I really liked it. I emphasises my point of view!

I am a final year student and this year I have to write my dissertation.
I have chosen to write about the "Identity Card in Modern Britain".

The aim of this research is to try and understand why many Britons are against the Identity Card.
I am from Belgium and I have always had an ID card since the age of 12. There is no debate in Belgium about having the ID card so for me it's quite odd for a country not to have one.

Also part of my research is to emphasise the increasing use of loyalty cards and such other cards on a daily basis.
Cards such as the Oyster card, which allows the TFL group to see where you are going and when, the Nectar card, which sets a routine on your purchases in stores and Library cards, which can see what you read. These cards hold as much, if not more, power than the ID card.

Could anyone please explain to me the dislike for the ID card in Modern Britain?
