Seems, it started with Google advising the Fed.

In December 2019, noting the success of UPI, Google suggested the US Federal Reserve Board to follow UPI as example in developing FedNow,[22] a real-time payment system for United States.[23]
UPI is a modern marvel tbh. Can't praise it enough.
I agree. I hardly carry cash nowadays.
