<commit_before>#### Description

This is a Bitcoin point of sale application. It was mainly written to
demonstrate the use of the green address feature, but can also be used
independently of that. It is written in Python and works in combination with the
standard Bitcoin-Qt client. It is targeted at standard PC hardware, e.g. laptop
(used by merchant) + external monitor (facing the customer). The main mode of
operation is displaying a QR code with a Bitcoin URI to the customer and
listening - via Bitcoin-Qt - on the network for a matching Bitcoin transaction.
But the software also support the use of NFC hardware to transmit the Bitcoin
URI as well as receiving incoming transactions via Bluetooth. See a video of the
system in action at http://www.youtube.com/watch?v=o84SfChQ-S8 .
