Crazy idea… But how awesome would it be to have a map (on a per user basis) of your transaction locations
I.e. you could zoom out and see red - green zones depending on the amount of transactions in a given area so if you live in London there would be a red area whereas your weekend trip to Birmingham might only be yellow or green on the map
Just seemed kinda cool - if a little gimmicky!!
(Heat map is the word I was after)
