Can you clarify something? I thought FedNow was for settling up when I, as an ABC Credit Union customer, initiate a transfer of $5000 to you, a Chase customer. Now ABC needs to subtract it from my account, and if successful, tell the Fed to take money out of ABC's Fed account and put it into Chase's, and to tell Chase to expect $5000 (Transaction ID: XXXX?) and here's who it's for.
Does FedNow, or whatever batch job it is replacing, involve ABC telling FedNow "This is for a transfer from Jane Doe (SSN 123-45-6789) to Joe Bloggs (SSN 098-76-5432)"? As I imagined it, FedNow would only need to know what bank is sending and what is receiving.
