I find it funny that the article repeats several times the amount of data that square. Do you know who has more data? The bank where the business has its account ;)
That being said, the current process from banks seems old and not really clever to me
Square gets item level data on each merchant. That means exactly what was sold and when. Plus, they get info about who bought it and can see things like a buisness suddenly getting huge numbers of new buyers as opposed to returning, etc.
But at least with Square we have relatively more transparency about their activities and intentions with such data. So while it may not literally be more, it's like functionally more?
I think the main point trying to be made there was that there is nothing stopping banks from doing something similar. In other words the "data" the article keeps mentioning isn't the advantage that makes this possible for Square.
The problem is most banks don't have the technology to scan a customer's bank account and decides his/her credit worthiness. That's how antiquated banks are and they wouldn't touch anything subprime after 2008 financial crisis.
That being said, the current process from banks seems old and not really clever to me
