The new Key website is a bit cleaner allowing you to see your balance a little better. The spreadsheet type grids are gone. It's a lot easier to add funds to your travel wallet.
The trip history is easier to read and understand. Even the autoload option is explained better. It avoids you tapping your card on a vehicle only to realize you don't have enough money loaded and could possibly be in a position where you can't reload.
The dispute history shows all your requests. Septa probably should rename it so it sounds more positive. I have a request in there still pending since December when I was incorrectly charged for a trip when a key validator didn't work.
The help section now properly explains how the Convenience Pass will work after purchase.The Septa website never did. I still feel you should have the option to purchase the pass and activate it when you are ready, not necessarily on your next tap. My example always is I'm buying the pass for my child to use on Saturday. I want to purchase it now so I don't forget. They are doing a single trip to school of Friday but Saturday I have them running errands and I want the pass to start then.
