Multibit has it
[/quote]Chris beat me to it. It is very useful. Just click the button to copy/paste the .png QR code.

Oh, where were we on QR support? Was that something going to be incorporated in the default client?
[/quote]I don’t understand this use case. How would that work exactly?
Do I point my external USB webcam at my screen (I don’t own one, all my machines have had built in web cams for the past 5 years that you actually can’t point at the screen without a mirror), so now you’re adding camera support to the client too? Who would do this, when they could just cut and paste the address? Or click on the feathercoin:// link? Or use the payment protocol?
Seems like a solution in search of a problem, but maybe I’m just missing the use case.
[/quote]Multibit has it, it comes in handy at events say if you are charging for Beers you can just have the QR code on the screen and people can pay by scanning on their phones. It also has a copy/paste option for printout. I think it saves it to your drive as a PNG.
It’s just a convenience thing really, might be handy for merchants?
[/quote]Oooooooohhhhh. Showing QR Codes, not reading them! Got it.
This is already implemented in 0.6.4.4. What new features are being requested then?
[/quote]It is? I don’t see it.
Actually scanning QR codes on a laptop can be done but it’s really fiddly. There is software out there but it’s not convenient. The only use case I could think for that is if the Merchant wanted a POS that could issue refunds, where an external webcam acted as a kind of Barcode scanner like they have on tills. Though for security reasons you would probably want this as dedicated hardware and not on a mutli purpose machine that could be hacked.
[/quote]I feel like I’m taking crazy pills… am I using a different 0.6.4.4 client than the rest of the world?
Receive coins-> click on an address-> click on “Show QR code”.
And to be clear, the Payment Protocol solves the above listed problems a whole lot cleaner than QRCodes ever will.

[/quote]lulz, just noticed it. I don’t think I’ve ever visited the receive tab since I generated my initial addresses for sites months back … I’m a giver. ;)

The client can show QR codes but only on Windows! I have not compiled this into the Mac client yet, sorry :(
Poor Mac users, they pay twice the price for a computer and then get forgotten half the time. The Mac client does not handle the Feathercoin URLs either. I believe an installer is required for that to make the client responsible for handling the Feathercoin URLs. If anyone is familiar with this then please let me know.

Re: QR codes. not on linux source build
I have tested QR codes with my Linux QT build of v0.6.4.4
The \ receive coins \ show QR – no QR image is shown.
-
The same here.
I’ve built on Linux, with QR code enabled, but no QR Code shows up.

Okay that makes sense then. Totally my bad, I run wallets on my Mac and Linux machines but try to keep my Windows stuff away from crypto, so there’s no way I could know. Sorry for my confusion!

[/quote]Yeah, I’ve done it plenty of times in the past. Used to make VPN clients that would launch and get their credentials from a protocol handler on Mac, Linux, and Windows.
Everything you need to know is here. Pretty straight forward. Don’t need an installer, you just need to run the client once.

I don’t have a mac any more though, so some brave soul who does will have to take the next part on.

[/quote]Have you built another client like Litecoin to see if the QR codes are working there?
I just want to make sure that it is the client and not your computer.

Linux (13.10) compiled versions from source -
Litecoin -Doesn’t have the option for QR codes, right click in receive coins.
whereas Feathercoin 0.6.4.4 QR code menu option is there on right click, but nothing happens.
-
Thanks for that Wrapper.
Wellenreiter and Lizhi I have added both of you again. Apologies Lizhi, I thought I had added you before.
The client compiles but is still broken by the changes to the key so is currently no good. The commit that broke compatibility is linked in below.
https://github.com/bitcoin/bitcoin/commit/dfa23b94c24aae6466152fccbe896ba5dc0e97b4

can you add me to the repository. user: groll
I will take a look but as usual my time is limited.
-
Hi Groll / Bush,
Re: Crowd development.
If you can think of any way I can help, test compiling, looking into some function / patch you need more info on / stuck on (history) or some such. Shout out.
-
groll, I have now added you to the repo. The commit that broke ACP and CAlert is as follows.
https://github.com/bitcoin/bitcoin/commit/dfa23b94c24aae6466152fccbe896ba5dc0e97b4
This made way for HD Wallets. We could simply reverse the commit but I would say that we make ACP and CAlert compatible with the changes to OpenSSL and include HD Wallets in this release.
Before the client downloads the block chain it appears fine.

[/quote]Thanks Wrapper. There should be a whole lot of testing soon. Right now the client compiles but crashes when the blockchain starts downloading with the following assert error. Be careful with this release as the wallets are not backwards compatible afterwards. Make sure you have a backup first.

Hierarchical Deterministic Wallets (11-2-2012)
https://en.bitcoin.it/wiki/BIP_0032
The Bitcoin reference client uses randomly generated keys. In order to avoid the necessity for a backup after every transaction, (by default) 100 keys are cached in a pool of reserve keys.
Deterministic wallets do not require such frequent backups, and elliptic curve mathematics permit schemes where one can calculate the public keys without revealing the private keys. This permits for example a webshop business to let its webserver generate fresh addresses (public key hashes) for each order or for each customer.
