Bank Records keeps a record of who moves funding around

Could do it like a statement, where you could log into your account on an ATM and see every paycheck deposit, every withdraw.

Maybe have the credit transfer devices do that, and print a paper receipt as well. Prove to Sec your firearm was legally purchased from a shady merchant.

There's some infrastructure in place for this to be done on the mainframe, iirc there's already an access code in the code for banking. I would absolutely love it if someone took the time to have this connect to the wired network (so send a packet for every transaction) and be stored on the mainframe for people to look at and potentially edit. Statements could then pull from this master list.
