1. Requirements

• Python 2.7.x
• virtualenv 1.11.x
• MySQL 5.6.x
• USB / Serial RFID Reader (see below)

2. Set up a python virtual environment, grab the source and pip install the requirements.txt file included:

    $ mkvirtualenv ShopIdentifyer
    $ workon ShopIdentifyer
    $ cd ShopIdentifyer
    $ pip install -r requirements.txt
   

3. Additionally, the system needs a ./identity/config.py file with the following properties:

    ENCRYPTED_STRIPE_TOKEN = 'encrypted-token'
    ENCRYPTED_DATABASE_PASSWORD = 'encrypted-password'
   
    DATABASE_USER = 'root'
    DATABASE_HOST = 'localhost'
    DATABASE_PORT = 3306
    DATABASE_SCHEMA = "shopidentifyer"
   
    STRIPE_CACHE_REFRESH_MINUTES=60
   

Please not that some of these properties are encrypted. When the web server starts up, it will prompt you for a decryption password. This is the same password that you will use to encrypt the properties using the tool in ./identity/crypto/crypt.py. The instructions for use are pretty straightforward:

$ python crypt.py

Usage: crypt.py enc <plaintext> <passphrase>
crypt.py dec <encrypted> <passphrase>

In addition to the Flask web application, there is an out of process daemon that listens for incoming RFID swipes on a given serial port, and then pushes them into the system.

The daemon is located in ./serial_remote/serial_listener.py and can be started as follows:

$ python serial_remote/serial_listener.py start

Please note that this assumes you have already set up a virtualenv with the requirements.txt satisfied.

Inside of ./serial_remote/config.py, you can change the value for the RFID serial device. My reader shows up as:

/dev/tty.usbserial-A800509r
