# This is a very basic script to backup oyster card data to a scraperwiki vault
# Notes:
# 1) You need an oyster card that has been registered on tfl.gov.uk
# 2) This script requires you to enter your username and password (this about what that means before progressing, and do so at your own risk)
# 3) This script should be run in a PRIVATE SCRAPERWIKI VAULT ONLY https://scraperwiki.com/pricing/ not a public scraper, or the world will know your password
