    I've created a JavaScript user interface for bitcoin. It's project page is located at:

    http://tcatm.github.com/bitcoin-js-remote/

    bitcoin-js-remote is a user interface for Bitcoin written in JavaScript. It works in most modern browsers as well as on Android and iPhones. If run on an Android phone it can scan QR codes containing addreses to send Bitcoins to! If you don't own an Android device, you can still enter raw bitcoin: URIs in a textbox.

    For SSL support a small server side script written in Python is required.

    • SSL for secure communication
    • Display QR code with address
    • Scan QR codes (Android only)
    • Supports multiple accounts
    • Android and iPhone support
    • Send and receive Bitcoins
    • List transactions

    New feature: Display address as QR code and scan QR codes on Android phones. This makes phone2phone transfer of bitcoins possible without having to enter addresses.

    i don't know how to get this running yet, but i can tell this is really great already! i have two questions:

    1) can you (or anybody capable) put together a step-by-step guide with pictures that shows a person who has never heard of Bitcoin how to get this running? If somebody knows how to make software installers for unix/linux, mac, and windows, that could make this project go viral since you can manage your account from a cell phone.

    2) is there a way to use virtualization efficiently and securely such that each person can have bitcoind run on the same physical server? could i run the server service in the cloud and have the data securely encrypted so that nobody could access my wallet.dat file except me? if so, this could be a virtual bank that securely maintains wallet.dat files, with the clients' trust that the virtual bank will keep the wallet.dat file secure and untampered.

    here is a qr-code generator for the software to read: http://qr.ma.eatgold.com/
    it supports specifying an amount to be sent. the js-software can implement this quite easily.

    Can we first please stick to one URI scheme? I don't want to parse QR codes for three different possible schemes.

    I prefer x-btc.

    I think this is about adoption. If you start using xbtc that would count in its favor.

    I personally would prefer the shortest possible, as this keeps the qrcodes small. x-btc mandates an action to be specified ("store" or "send" currently) and also mandates the "addr=" part in front of the adress, both which I consider to be redundant.

    I like the simplicity of bitcoin:xxxxxxxxxxxxx plus very much approve of its accessibility. Should someone from the outside happen to see such a uri, the protocol name already gives a description. A quick google search should then do the rest. x-btc sounds much more cryptic, the chance that s/1 gooogles that out of curiosity are much slimmer. Also, very likely, what s/he will find are mostly technical specifications. Not a good introduction to bitcoin.

    Let's move this discussion over to http://bt.irlbtc.com/view/2705.0 as it fits better there.

    Added bitcoin: URI support for QR codes (you can even enter raw bitcoin: URIs if you don't have a Android phone!)

    One suggestion: I think the license you are using is the MIT license; however neither the files nor the project page mentions, which specific license you are using. Please add the type of the license to your project page and the files.

    Fixed (integration branch for now)

    I would like insert a private key from QR code. So I could print a wallet on paper and give this paper to another person. He could scan this QR code with an android phone, check the value and transfer the bitcoins to his wallet.

    First: Please discuss this in another thread. This is only for js-remote!

    This is a feature that needs support in bitcoin itself. Once there are RPCs I can add such a feature to js-remote.

    This is really great, the perfect UI for a phone!

    I just tested the new version on the demo page and the account handling looks great.
    Unfortunately, there seems to be a problem with sending, it always says "Invalid account name"...

    Just wanted to let you know. Again, great work, and many thanks, tcatm! Smiley
