Topic: Launch of BitPay, worlds first smartphone-ewallet for bitcoins (Read 9919 times)

Wow this actually looks legit and useful!

Thank you for clearing that up for me sir.


If this were possible you could print a pseudo-wallet on paper and hand it to some one like cash. You could also conceivably use it like a debit card for BTC, but as previously noted security would be minimal.

One additional question I had is, could a minimal wallet file be created that would fit within a single QR code? If this were possible, this could help take the responsibility for the security of BTC exchanges off of the exchange services and leave it completely up to the end users. As a retailer my main apprehension in taking bitcoin is the fact that if my server was compromised I would then be responsible for all the lost BTC. This places the risk back onto the user and frees up service providers resources for development, and also has the additional benefit of decentralizing the system with an open physical exchange platform.

Feature suggestion: an option to enter value in other currencies (EUR, USD) with automatic conversion

There was a thread about a single address + private key encoded qr code (http://forum.bitcoin.org/index.php?topic=3716.20), so you can scan and own that bitcoin address (+private key!) . First thing you'll do is to transfer the coins, because the guy who generated the private key could could transfer the coins, if you wants to...

But this won't work for BitPay, because it is not a fully bitcoin node, so some web service would have to offer a "private key spend coins service" it could use.

working with bitcoin uri, just containing the address and a web service like instawallet.org is simple, easy and fast. I like it for smart phones.

I am working on a BitPay clone, that would be easily portable to android and Iphone (well, don't know what the apple market will say ) and some other, if I'll find alternatives for the ZXing QR code scanner library...

What "rival application" are you refering to?

Wow, this is a really great app! Thanks alot for making it! Here in Sweden time is growing really short for this: a rival application not using bitcoin just came online. If it becomes popular than the moment may be lost. Are there mobile pay apps in other countries too?

I dont understand what you want to use this for?


B£ackBerr¥ is as proprietary as Mi$ro$oft and App£e so I have no interest of developing for thoes platforms.

private keys are 256bits long.  default wallet generates 100 pool keys plus whatever keys you've manually created - so say, 110 keys.  That's 3250bytes.

Maximum data storage of a QR code is 2953 bytes¹

Will

Any chance of a Blackberry version?

Please excuse me for being an ignorant newb here... but what is stopping people from just making a wallet file encoded in a QR code?

Oh, sorry. I forgot that, now its about BitPay instead

OK.  Maybe don't link to it in your signature for now then, if you know it's not working.

Thx. Please add issues or post comments to github.

I think that the gui sucks right now, so if you have any ideas, please post these here.

Good improvements.  Already better.

Crash after "From Camera" returns seems fixed; and I tried it and it read a QR code successfully.

Now bitpay version 0.12 is released and a lot of the issues we discussed is now solved

Hello dooglus, read what I wrote at the end of this thread
http://forum.bitcoin.org/index.php?topic=6967.msg317910#msg317910


This is very interesting, we need to find what makes your phone crash when running bitpay. Is it possible for you to make a video about it? Please write what version of Android and QR you are using.

Thanks Warpi

I reinstalled the barcode scanner but it still makes bitpay crash...

Yes, we have been thinking about this aswell, but it requires a little rethinking when it comes to the userinterface, so its probably more work than one could think at first.

Good point
https://github.com/warpi/BitPay/issues/15


Agree, me myself is a pedant so I will naturally make sure these things will be solved in future, no need of issue.


Yes, we have in vision to have multiple accounts, but showing where the eWallet is located is not important on every page (more important is what account is selected). But as of now, I just wanted to make some advertising for InstaWallet.org for making this application possible at this time, but in future, I dont think its necessary.


As of now, we just display what is on InstaWallet.org without interpretation. This issue will naturally be solved when doing that.


That would be awesome. I dont know exactly how android works, maybe its possible to integrate a widget into the application?

Great. Its also possible to comment the issues to make a better description or purpose better solutions.


Thanks, same here I love the feeling of always being able to send money to anyone with a android telephone from now on


Yes, regarding replacing credit card machine. Me and leifi have been discussing how to make this application both supporting people 2 people transaction, but aswell enabling easy for merchant use. Hopefully, this is possible with the same application.


Hello kwukduck,

If you want to withdraw you money, just to go "credits" tab, and write the InstaWallet.org url displayed at the bottom at your computer. At this homepage, you could easly withdraw your money to another account.

It seems there is something wrong with the QR-reader. Have you downloaded this from the market?

crashes when i try to send btc
after i scanned code with the barcode scanner it gives Force Close

so i can receive money but not get it out :/
