I’ve been using my Mondo card pretty much every day since I got it when travelling around London.
I noticed this morning that TFL did another active card check (despite me using it yesterday); just out of interest do they regularly do this?
Hey Alex,
As you’ve noticed TfL is a bit weird with the way they charge (hopefully at some point we’ll be able to integrate more fully and show you up to date charges, journey details etc. 
). You will generally get another active card check after 14 days of inactivity or when you’ve paid off unpaid fares, but they’re quite unpredictable!
