> Wish we could do the same for the credit card companies. Would be great if the Federal Government could intervene in some way to have Visa / Mastercard / American Express / Discover use the same API interface for payments. Would dramatically increase competition for providers.

If FedNow can fit in with ApplePay, then it can displace credit cards in the first place! The corollary I’m drawing, is from India where “UPI” payments (something similar to FedNow) was launched about 7 years ago and today is the more dominant payment mode than credit cards.
