It’s a great idea to show where and when a transaction has been made.
It would be really interesting to make better use of this, much like they do when you’ve been on holiday.
Use case: I’m meeting a friend for dinner in a location that I havn’t been for a while. I know that last time I visited, I went to this amazing restaurant but can’t remember what it’s called.
How brilliant would it be to browse a map with an overlay of restaurants I’ve been in the area?
I’m sure you can do this on Google Maps and TripAdvisor by saving your favourite places you’ve been to or would like to go. The fact that Monzo already knows where I’ve been would make this much easier.
