As someone whos only been to london for one weekend within the past decade im quite shocked that someone who im assuming has more experience of it than me has hit this problem....
The machines tell you how much you have left on when you swipe out, so surely if you are a heavy user you should whack more on when it hovers around £5?!?
I found it easy enough keeping track of mine!
An annoyance that you cant check yea, but its assumed that people look when they swipe out i guess
