Sorry for the long reply, no worries I don&#x27;t take it as a critic.
It&#x27;s actually more like what amagumori said:
<i>the dichotomy is &quot;everyone in the checkout line can see what i&#x27;m buying&quot; vs. &quot;all people who know my first and last name can view my entire credit card transaction history&quot;.</i><p>If you see my license plate in the street today, I wouldn&#x27;t care at all. I wouldn&#x27;t be fine if you published that information in a &quot;where is everybody right now&quot; wiki.
From that wiki a stalker would have it really easy to ruin my life; a burglar could break in at the good moment; an employer could know I visited their concurrent, probably for an interview; I go to this church&#x2F;mosque&#x2F;synagogue&#x2F;... : now you know my religion;the neighborhood association could see I have &#x27;too many&#x27; (for their standard) friends (or AirBnB customers?) visiting; marketers could see I go often to store X,Y, on vacation to Z, that I&#x27;m more of a Fast food Mc lover than a BK, ...<p>Also:
<i>So taking a photo of (or making a memory of having seen) doesn&#x27;t violate your privacy</i> . For many Europeans countries it does violate the privacy, if that photo has no public information purpose. For instance: <a href="http:&#x2F;&#x2F;uk.practicallaw.com&#x2F;7-573-6346" rel="nofollow">http:&#x2F;&#x2F;uk.practicallaw.com&#x2F;7-573-6346</a>
