If you read the linked article by the IMF you start to get it, bunch of ECB economists exploring innovation in financial products and writing a meaningless blogpost about it. Bunch of buzzwords, nothing interesting.

In their defense, they write: “Fintech resolves the dilemma by tapping various nonfinancial data: the type of browser and hardware used to access the internet, the history of online searches and purchases.”

So it seems they’re not recommending this usage of data persee, but just say fintech is already doing this.
