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 Viena, as well as the recent Bitcoin in the Beltway conference in Washington DC.

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.

• The keys are never exposed to the web
• The wallet uses true high level entropy
• The wallets only exist on paper.

Think of it as being able to create your own bank deposit certificates, while keeping only a bit of spending cash on your Android wallet.

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.
