Preferably under 100 bytes.  You will see\n\u003e increasingly poor operating in varying light conditions, such as\n\u003e paying via QR code on a printed receipt in a pub at night.  That was\n\u003e one of the motivations for BIP 73.\n\u003e\n​Hmm, in this case I think base43 discussion is irrelevant. Even with best\nspace utilization we can get ​we will not be able to fit in anything bigger\nthan a smallest unsigned payment certificate. And that is not so useful. So\nprobably we should stick with BIP73 approach and bluetooth URI scheme we're\ninventing.\n\n\n\n\u003e\n\u003e\n\u003e On Thu, Mar 20, 2014 at 4:09 AM, Andreas Schildbach\n\u003e \u003candreas at schildbach.de\u003e wrote:\n\u003e \u003e Afaik, BIP73 needs an external server (the web server).\n\u003e\n\u003e Yes.
