All you know is that\n*someone* within 100m is requesting bitcoin at a certain address. Not\nnecessarily who. The *name* is both optional, and possibly just a *handle*\nof the user. If I'm sitting 5 ft away from someone at dinner and wanted to\npay them via BLE, I might see \"Monkey Dude\" on my list and simply ask him\n\"is that you?\" If so, I send it. If there are two \"Monkey Dude's\" Then I\nhave to bother with the address prefix, but not otherwise.\n\n\n[image: logo]\n*Paul Puey* CEO / Co-Founder, Airbitz Inc\n+1-619-850-8624 | http://airbitz.co | San Diego\n\u003chttp://facebook.com/airbitz\u003e  \u003chttp://twitter.com/airbitz\u003e\n\u003chttps://plus.google.com/118173667510609425617\u003e\n\u003chttps://go.airbitz.co/comments/feed/\u003e  \u003chttp://linkedin.com/in/paulpuey\u003e\n\u003chttps://angel.co/paul-puey\u003e\n*DOWNLOAD THE AIRBITZ WALLET:*\n  \u003chttps://play.google.com/store/apps/details?id=com.airbitz\u003e\n\u003chttps://itunes.apple.com/us/app/airbitz/id843536046\u003e\n\n\n\n\nOn Thu, Feb 5, 2015 at 1:46 PM, Eric Voskuil \u003ceric at voskuil.org\u003e wrote:\n\n\u003e BLE has an advertised range of over 100m.\n\u003e\n\u003e http://www.bluetooth.com/Pages/low-energy-tech-info.aspx\n\u003e\n\u003e In the case of mass surveillance that range could most likely be extended\n\u003e dramatically by the reviewer.
