Hey all,

I've built a simple point-of-sale device that facilitates bitcoin transactions. It consists of a numpad and character display for a 'cashier' and a small LCD display for the 'customer'. This device simply allows the cashier to enter a dollar amount on the keypad and have a QR code generated for the customer. The device will display a confirmation screen once it receives the unconfirmed transaction from the customer.

Here's a small demonstration: http://youtu.be/3uetgK0brgA

I figure something like this would be great for a small business to be able to use to easily, yet professionally accept bitcoin -- an all-in-one solution that can just be dropped next to a cash register and work. I have seen plenty of tablets being used as point-of-sale devices, but that involves pecking in the transaction total and awkwardly passing the tablet back and forth. This is just a stationary, dedicated unit.

My friend will be using one of these devices at the Bitcoin Conference next weekend!
Look out for BitcoinNotBombs.

Developy Stuff:
I put the code and build instruction on github: https://github.com/WeMeetAgain/btcpos
I'll keep upgrading this code in the future.
I've also included some security considerations in the README.

This box simply uses the blockchain.info API to handle bitcoin address generation(a new one for each transaction), listening for transactions, and sending bitcoins. No information is stored on the device except the information necessary to communicate with blockchain.info and the address to which to send the bitcoins.

Let me know what you guys think.

That looks great! It would be more awesome if it get integrated with a credit card terminal or similar.
