The UNoffficial WisCard App
What is WisCard you ask? It is UW-Madison's ID/Cash card. So why this app? It followed over from Money Manager BETA; it is a way to see transactions completed through WisCard and export them to desired formats.
Due to the lack of public facing APIs, I had to resort to injecting javascript to WisCard website, and scraping HTML at runtime
Needless to say, WisCard department was not happy with it, and did not grant permission to deploy the app on Play Store. So it's been sitting on the shelf ever since!
