How does Blippy get its data

I was wondering how Blippy is able to get my data? It requires me to put in my bank name, bank card number and password, so is it doing a simple website scrape by logging in?

My bank, however also requir开发者_运维问答es a seperate passphrase as well. How does it get around that?

Can urllib and such libraries be used in Python to replicate Blippy functionality?

Blippy probably uses a service like Yodlee to interface with the bank rather that simple screen scraping. Having said that it is possible to implement similar functionality by combining urllib, BeautifulSoup and Regex modules.
