So I'd say definately go for Bluetooth. Yes, it's part of the plan. Just again - I need to make sure we support all major wallets. And no other wallets actually support NFC by now, not talking about bluetooth. So I imagine we will decide and implement together some solution here, both on the wallet and POS sides, but I will have to keep URI method and even QR codes for backwards compatibility, and wait for other main wallets to accept innovations before we will be able to completely switch to it. As I said earlier - bluetooth support for my POS is not a problem, we can plug it in easily and make it work. Support among all hardware/software and polished user experience - this is a main thing here really. Sure, take all the time you need. All I wanted to say is you don't need to break Bitcoin URI compatibility in order to support direct payments via Bluetooth. It's simply an add-on, both in the BIP21 and the BIP70 cases. -- Subversion Kills Productivity. Get off Subversion Make the Move to Perforce. With Perforce, you get hassle-free workflows.

2014-03-06 12:26 GMT+01:00 Andreas Schildbach andr...@schildbach.de: In current phone implementations, the screen must be on already for NFC to be active. Also it must be unlocked, although I certainly hope future OSes will allow payment apps on the lock screen, just like they allow music players. Just a small input to this point: On Android 4.4 the new host card emulation (HCE) feature (aka: the phone emulates a ISO-DEP Smartcard and processes ISO7816-4 APDU commands like a Smartcard would do) only works when the display is on, but even when the screen is locked (can be changed with android:requireDeviceUnlock in Manifest). See here for detailled specification: http://developer.android.com/guide/topics/connectivity/nfc/hce.html Using the HCE API on Android 4.4 also has the beauty that any app that registers itself for HCE and sets its category to CATEGORY_PAYMENT in the Manifest automatically shows up in Adroid's system settings under Tap Pay (where a user would expect payment applications). -- Subversion Kills Productivity.

Re: [Bitcoin-development] Is this a safe thing to be doing with ECC addition? (Oracle protocol)

To rephrase, imagine I gave you an ECC public key ed_pub, you gave me back a public key odinn_pub of your own devising, then I paid some money to the address resulting from add_pubkeys(ed_pub,odinn_pub) [1]. Can anyone either: a) Think of a way that Odinn could make an odinn_pub such that they could spend the resulting money without having ed_priv. b) Opine, somewhat knowledgeably, that this probably wouldn't be an easy thing to do, and they wouldn't be alarmed to see people running software that did this kind of thing.
