@ toadwarrior - Re: I don't quite understand
<quote>You aren't forced to get a clubcard or nectar card and cctv isn't publically available. Where as what google is doing is done without permission on a massive scale and publically assessible.</quote>
You have a point there, although the questioned Wifi data is, as far as I know, not available.
Nevertheless, I think that the general public does not realise how much data is gathered through their 'rewards' card, just as they don't realise how much Google gleaned from their drive-by; which is, I would bet, on average much less.
Google did it without consent, Nectar does it by exploiting that most people do not see past the 'rewards' bit and willingly supply the companies with consumer data that would otherwise be expensive to gather.
Do you think that the same amount of people would sign up if Nectar's adverts would state that:
'We record your shopping behaviour on behalf of over 500 companies and sell the results to them so they can design their advertising campaigns easier and cheaper and present their goods in a way that reduces the risk of losing money by having to lower the prices of stuff you otherwise won't buy. In return we grant you a discount of up to 2%*' ?
I'm not sure...
Anyway, I don't need to get a card, as you said, and I'm fine with that. Let's drink to that.
*I just checked: You can pay a return flight from London to Barcelona on easyjet with Nectar points. To gain these, you have to spend around £23.000 at Sainsbury's. Wow.
