It would also require that a Sender have internet\nconnectivity to get the payment protocol info. BLE could enable payment w/o\ninternet by first transferring the URI to from Recipient to Sender. Then in\nthe future, we could sign a Tx and send it over BLE back to the recipient\n(who would still need internet to verify the Tx). This is an important use\ncase for areas with poor 3G/4G connectivity as I've experience myself.\n\nAlso, due to Android issues, NFC is incredibly clunky. The URI Sender is\nrequired to tap the screen *while* the two phones are in contact. We\nsupport NFC the same way Bitcoin Wallet does, but unless the payment\nrecipient has a custom Android device (which a merchant might) then the\nusage model is worse than scanning a QR code. BLE also allows people to pay\nat a distance such as for a donation to a live performer. We'll look at\nadding this to the Motivation section.\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\nFrom: Andreas Schildbach \u003candreas at sc...\u003e - 2015-02-05 13:47:04\n\nThanks Paul, for writing up your protocol!\n\nFirst thoughts:\n\nFor a BIP standard, I think we should skip \"bitcoin:\" URIs entirely and\npublish BIP70 payment requests instead. URIs mainly stick around because\nof QR codes limited capacity. BIP70 would partly address the \"copycat\"\nproblem by signing payment requests.\n\nIn your Motivation section, I miss some words about NFC. NFC already\naddresses all of the usability issues mentioned and is supported by\nmobile wallets since 2011. That doesn't mean your method doesn't make\nsense in some situations, but I think it should be explained why to\nprefer broadcasting payment requests over picking them up via near field\nradio.\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150205/77152aa7/attachment.html\u003e"}
