It would also require that a Sender have internet&#xA;connectivity to get the payment protocol info. BLE could enable payment w/o&#xA;internet by first transferring the URI to from Recipient to Sender. Then in&#xA;the future, we could sign a Tx and send it over BLE back to the recipient&#xA;(who would still need internet to verify the Tx). This is an important use&#xA;case for areas with poor 3G/4G connectivity as I&#39;ve experience myself.&#xA;&#xA;Also, due to Android issues, NFC is incredibly clunky. The URI Sender is&#xA;required to tap the screen *while* the two phones are in contact. We&#xA;support NFC the same way Bitcoin Wallet does, but unless the payment&#xA;recipient has a custom Android device (which a merchant might) then the&#xA;usage model is worse than scanning a QR code. BLE also allows people to pay&#xA;at a distance such as for a donation to a live performer. We&#39;ll look at&#xA;adding this to the Motivation section.&#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;From: Andreas Schildbach &lt;andreas at sc...&gt; - 2015-02-05 13:47:04&#xA;&#xA;Thanks Paul, for writing up your protocol!&#xA;&#xA;First thoughts:&#xA;&#xA;For a BIP standard, I think we should skip &#34;bitcoin:&#34; URIs entirely and&#xA;publish BIP70 payment requests instead. URIs mainly stick around because&#xA;of QR codes limited capacity. BIP70 would partly address the &#34;copycat&#34;&#xA;problem by signing payment requests.&#xA;&#xA;In your Motivation section, I miss some words about NFC. NFC already&#xA;addresses all of the usability issues mentioned and is supported by&#xA;mobile wallets since 2011. That doesn&#39;t mean your method doesn&#39;t make&#xA;sense in some situations, but I think it should be explained why to&#xA;prefer broadcasting payment requests over picking them up via near field&#xA;radio.&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150205/77152aa7/attachment.html&gt;</html></oembed>
