What is the significance of this? Tracking who has what money?

• jacobolus 10y ago
  Purchases you make with cash you got from an ATM become traceable to your bank account.

    That only works if every single shop/service tracks the serial numbers, otherwise you have no way of knowing if they were exchanged somewhere in between.

      It's a very small graph.

      You don't need to step very far from cash in hand before this becomes not just viable but ridiculously easy. Just feed notes individually into your bank-approved combined till/safe/note scanner.

        I think you understimate the effort of requiring everyone - from large chains to street food stalls - to always use note scanners. Bank? How many people selling fruit from their cart even use banks for their sales?
