All you know is that&#xA;*someone* within 100m is requesting bitcoin at a certain address. Not&#xA;necessarily who. The *name* is both optional, and possibly just a *handle*&#xA;of the user. If I&#39;m sitting 5 ft away from someone at dinner and wanted to&#xA;pay them via BLE, I might see &#34;Monkey Dude&#34; on my list and simply ask him&#xA;&#34;is that you?&#34; If so, I send it. If there are two &#34;Monkey Dude&#39;s&#34; Then I&#xA;have to bother with the address prefix, but not otherwise.&#xA;&#xA;&#xA;[image: logo]&#xA;*Paul Puey* CEO / Co-Founder, Airbitz Inc&#xA;+1-619-850-8624 | http://airbitz.co | San Diego&#xA;&lt;http://facebook.com/airbitz&gt;  &lt;http://twitter.com/airbitz&gt;&#xA;&lt;https://plus.google.com/118173667510609425617&gt;&#xA;&lt;https://go.airbitz.co/comments/feed/&gt;  &lt;http://linkedin.com/in/paulpuey&gt;&#xA;&lt;https://angel.co/paul-puey&gt;&#xA;*DOWNLOAD THE AIRBITZ WALLET:*&#xA;  &lt;https://play.google.com/store/apps/details?id=com.airbitz&gt;&#xA;&lt;https://itunes.apple.com/us/app/airbitz/id843536046&gt;&#xA;&#xA;&#xA;&#xA;&#xA;On Thu, Feb 5, 2015 at 1:46 PM, Eric Voskuil &lt;eric at voskuil.org&gt; wrote:&#xA;&#xA;&gt; BLE has an advertised range of over 100m.&#xA;&gt;&#xA;&gt; http://www.bluetooth.com/Pages/low-energy-tech-info.aspx&#xA;&gt;&#xA;&gt; In the case of mass surveillance that range could most likely be extended&#xA;&gt; dramatically by the reviewer. I&#39;ve seen  WiFi ranges of over a mile with a&#xA;&gt; strong (not FCC approved) receiver.&#xA;&gt;&#xA;&gt; WiFi hotspots don&#39;t have strong identity or a guaranteed position, so they&#xA;&gt; can&#39;t be trusted for location.&#xA;&gt;&#xA;&gt; e&#xA;&gt;&#xA;&gt; On Feb 5, 2015, at 1:36 PM, Mike Hearn &lt;mike at plan99.net&gt; wrote:&#xA;&gt;&#xA;&gt; This sounds horrible. You could basically monitor anyone with a wallet in&#xA;&gt;&gt; a highly populated area and track them super easily by doing facial&#xA;&gt;&gt; recognition.&#xA;&gt;&gt;&#xA;&gt;&#xA;&gt; We&#39;re talking about BLE, still? The radio tech that runs in the so called&#xA;&gt; &#34;junk bands&#34; because propagation is so poor?&#xA;&gt;&#xA;&gt; My watch loses its connection to my phone if I just put it down and walk&#xA;&gt; around my apartment. I&#39;m all for reasonable paranoia, but Bluetooth isn&#39;t&#xA;&gt; going to be enabling mass surveillance any time soon. It barely goes&#xA;&gt; through air, let alone walls.&#xA;&gt;&#xA;&gt; Anyway, whatever. I&#39;m just bouncing around ideas for faster user&#xA;&gt; interfaces. You could always switch it off or set it to be triggered by the&#xA;&gt; presence of particular wifi hotspots, if you don&#39;t mind an initial bit of&#xA;&gt; setup.&#xA;&gt;&#xA;&gt; Back on topic - the debate is interesting, but I think to get this to the&#xA;&gt; stage of being a BIP we&#39;d need at least another wallet to implement it?&#xA;&gt; Then I guess a BIP would be useful regardless of the design issues. The&#xA;&gt; prefix matching still feels flaky to me but it&#39;s hard to know if you could&#xA;&gt; really swipe payments out of the air in practice, without actually trying&#xA;&gt; it.&#xA;&gt;&#xA;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150205/b562bf05/attachment.html&gt;</html></oembed>
