You could basically monitor anyone with a wallet in&#xA;&gt; a highly populated area and track them super easily by doing facial&#xA;&gt; recognition.&#xA;&gt;&#xA;&#xA;We&#39;re talking about BLE, still? The radio tech that runs in the so called&#xA;&#34;junk bands&#34; because propagation is so poor?&#xA;&#xA;My watch loses its connection to my phone if I just put it down and walk&#xA;around my apartment. I&#39;m all for reasonable paranoia, but Bluetooth isn&#39;t&#xA;going to be enabling mass surveillance any time soon. It barely goes&#xA;through air, let alone walls.&#xA;&#xA;Anyway, whatever. I&#39;m just bouncing around ideas for faster user&#xA;interfaces. You could always switch it off or set it to be triggered by the&#xA;presence of particular wifi hotspots, if you don&#39;t mind an initial bit of&#xA;setup.&#xA;&#xA;Back on topic - the debate is interesting, but I think to get this to the&#xA;stage of being a BIP we&#39;d need at least another wallet to implement it?&#xA;Then I guess a BIP would be useful regardless of the design issues. The&#xA;prefix matching still feels flaky to me but it&#39;s hard to know if you could&#xA;really swipe payments out of the air in practice, without actually trying&#xA;it.&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150205/f97ddd7e/attachment.html&gt;</html></oembed>
