As seen @ DEF CON 2013 – the BitcoinBriefcase is a self-contained Bitcoin vending machine –
Once the user’s last coin is inserted, he pushes the LED button to let the system know to start the Bitcoin magic. A random number is generated using the hardware pseudorandom number generator on the raspberry pi and is used as the private key for this Bitcoin transaction. A transaction for the inserted value is broadcast to the public Bitcoin network, and the transaction information including the private key, the Bitcoin address, and associated QR codes are printed out on the thermal printer.
