Isn't there a way to just use a pic of the QR code taken with the camera?
No, and it would probably not work out that well. If the image is slightly out of focus you would have to do multiple (annoying) iterations. "Live" scanning solves that. I tried different QR scanners, only one worked but it has no clipboard option. I think it's a Cyanogen issue.
This one always stores the scanned content on the clipboard: https://play.google.com/store/apps/details?id=com.google.zxing.client.android

Thanks, I've tried it but it didn't work with CyanogenMod (Galaxy S4). The only way for me seems to manually enter the addresses.

It's only a week until the Bitcoin in the Beltway conference takes place in Washington DC ( http://www.bitcoinbeltway.com/). It's being put on by Jason King of Sean's Outpost, who just finished running across USA (but is flying back, because he's not manly enough to walk here). Mycelium will be representing there too, where we will be demonstrating our brand new hardware called Mycelium Entropy. It's a small USB device that you plug into your printer, and it generates a totally random and secure paper wallet. We'll be launching the Kickstarter for it any day now (we ran into delays with the video, which, although not as interesting as the Mycelia in Wonderland one, is still pretty cool).

Stop making amazing products! D: Anyway, how would this device connect to a printer? I still have a perfectly fine old laser printer (which I use regularly), which is connect to my computer (a parallel port if I am not mistaken) with a massive connector. Is the Mycelium Entropy able to communicate with said printer? And what about drivers? A lot of printers have different kind of drivers, how will Mycelium Entropy handle that?

I still have a perfectly fine old laser printer, which is connect to my computer (a parallel port if I am not mistaken) with a massive connector. Would I be able to use Mycelium Entropy with that printer? Depends on your printer. If it can print pictures straight off your camera SD card for example (without the need for PC and drivers). Look for the slots. Parallel port does not sound promising though.

I updated my previous post with more questions ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) And no, it has no slots. Just a huge connector, that's all. I am going to assume that it won't be able to use Mycelium Entropy then ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

That's probably a serial port. You might be able to use an adapter.

Highly unlikely since the printer won't have the needed functionality in-built. The general process is described here (an example) http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02873650#N192No need for a PC and as such no need for drivers.

Sorry for the delayed reply. Mycelium Entropy plugs into the USB port that you typically find on the front of some printers, and is detected by a printer as just a flash drive with a photo on it. You would need to have a printer that can print photos directly off USB drives for it to work. A printer that uses a parallel port is a bit old XD

Great work on the app guys! Keep it up! I'm really excited for Entropy. Would it be possible to update the firmware in the future to print keys from a BIP32 seed? I realize updating it (if that's even possible) from an internet connected machine would kind of defeat the point of Entropy itself, but maybe it would be possible to download the update and then move it to an offline only machine and update from there. Bonus points if we can verify the update via PGP.

Today, Mycelium has announced the launch of an Indiegogo project for its Mycelium Entropy device. Mycelium Entropy is the newest addition to the Mycelium Bitcoin Wallet ecosystem, first announced at the Bitcoin2014 Conference in Amsterdam, and demonstrated at the Central Europe Bitcoin Expo in Vienna, as well as the recent Bitcoin in the Beltway conference in Washington DC. The project fundraiser was initially delayed when Kickstarter decided to deny it on the grounds that "Kickstarter's guidelines do not allow for offering money processing services." Attempts to explain that a hardware random number generator is not in any way a "money processing service" has failed, but the Mycelium team was not deterred, and we found a new place to host the fundraiser. Mycelium Entropy is a small, simple USB device that is designed specifically to generate paper wallets. All you do is plug it into a printer's USB port, and the device uses specialized hardware to create a random number with 256-bits of entropy. It then uses that number to generate a paper wallet with public and private keys, which your printer sees as a JPG photo that it can print directly from the device. This is currently the most secure way to create paper wallets, since the keys are never exposed to the web, use true high level entropy, and only exist on paper. For extra security, Mycelium Entropy can also create M-of-N split keys, where the private key is split up in such a way that you need two out of three parts to spend from an address. In this way, if one of your paper backups is lost or stolen, the thief still can't steal your coins, and you can still access them using the remaining 2 paper backups. Since the Mycelium Bitcoin Wallet has full support for spending from paper wallets, using Mycelium Entropy in combination with the Mycelium Bitcoin Wallet can be a very safe and easy way to store and protect your savings. Think of it as being able to create your own bank deposit certificates that you can keep in a safe, while keeping only a bit of spending cash on your Android wallet. With this combination, the idea of "Be Your Own Bank" comes much closer to reality, and becomes much easier as well. At this stage, the devices are fully functional, and need just a few minor software tweaks, such as fixing issues of incompatibility between US and European sized paper standards causing the headings on the paper wallet image to be cut off. Mostly minor things that will be resolved by the time we are ready to launch. Although the device hardware is open source, we need to raise money to be able to order them in sufficient enough quantities to make them cheaper for everyone, since mass production is much cheaper than ordering them one at a time. Also, about $1,500 of the money raised will go towards testing and compliance for these types of devices, like CE marks, FCC part 15 approvals, etc. While the devices are being developed, we will spend time testing printers and putting together a list of recommended printers to use with these, just to make sure that yours can handle this, or if it can't, to help you find the cheapest (and most secure) option you can get. You can read many more details, and see examples, on our Indiegogo page.

Will you present it on 1st July, at Vienna Metalab meeting? (Andreas?) EDIT: and can I help you with something there? @Mycelium Team: I'd also like to invite you on a beer! You already know at which place ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Sorry, we tried Kickstarter, wich would have used Amazon for credit card processing but they didn't like us selling financial-services-on-a-stick ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) BTW, you don't have to use a PayPal account if you don't want to. Just use the credit card option.
