Is amazing the number of digital transactions that take place on a given day. Are none of those transactions guaranteed or only those transactions in excess of a stated $ amount ?
I think they’re all guaranteed to whatever level the issuing bank guarantees anything. None of it is terribly difficult. That’s part of why it took over. It’s all in the computers anyway. Your bank account, and all your transactions. If you get cash it’s still a digital transaction. If you write a check eventually it’s a digital transaction. Once the banks computerized that’s the stuff that mattered.
