&gt; I can&#x27;t help but wonder...how many real-world businesses could benefit from the same type of invasive tracking that online businesses seem to think they have a right to subject us with?
&gt; For some reason, though, we don&#x27;t allow that sort of privacy violation in our actual lives.
&gt; However, most real-world businesses manage to do quite well even with our rude dismissals of their desire to track us.<p>Are you sure you&#x27;re not being tracked? There are technologies like Prism[1] that allow stores to track people, where they go, how long they stay there, etc. On the lower-tech side, point cards[2] are also used to track purchasing habits.<p>[1] <a href="https:&#x2F;&#x2F;prism.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;prism.com&#x2F;</a><p>[2] <a href="http:&#x2F;&#x2F;consumerist.com&#x2F;2012&#x2F;02&#x2F;17&#x2F;target-figures-out-teen-girl-is-pregnant-before-her-father-does-sends-helpful-coupons&#x2F;" rel="nofollow">http:&#x2F;&#x2F;consumerist.com&#x2F;2012&#x2F;02&#x2F;17&#x2F;target-figures-out-teen-gi...</a>
