"public spaces" may include shops and other private property open to the public. Shop owners may want to use it for marketing and blacklisting known shoplifters.
You're suggesting that shop owners use a Howitzer to shoot flies.
Using such technology for this purpose is a massive overkill and prone to abuse.
I already resent some of the tracking techniques used by shops today (i.e abusing my cell phone for their tracking). I hope that some enterprising citizens (I see organizations like the CCC) publish lists of shops employing such technology.
Because I, for one, wil make damn sure that they don't get my business. Not! one! penny!
By "shop owners may want to use it for marketing" you mean large companies that would love to build complete behavior profiles and then sell them?
Edit: Even if this is somehow restricted to small ago owners I don't think they have the right to have my identity because I setup into their shop. I do think a reasonable exception could be carved out to allow monitoring for a specific list of individuals who have been banned from the premises.
Please no. I find it annoying enough that I can't click on random youtube links for fear of being bombarded with viral trash for the next few weeks.
I really don't want to be bombarded by ads just because I looked into a window display for a bit too long.
