-A server creates a serial number with the bill's amount and sends it to a computer that prints the bill.
-User goes to a shop
-He gives the shopkeeper the bill.
-He scans it.
-The computer sends an HTTP request to the server to check if the bill is fake (or cloned), and to generate more bills (to return to the client, for example)
-The server checks it, and returns if its fake or not. It also returns all the serial numbers required by the client and mark the old bill's number as used.
-The computer prints the bills.
-The shopkeeper can now spend his money.
Well, let's compare this with floppies:
-You can only see the label
-You can't stack them in "printed floppies"
And I know you can simply put the serial number with the keyboard, but it's so much slower. Imagine doing that with a program that saves the printed page as a file. It would take so much longer than simply scan it.

Even if it does exist, what advantages does it enjoy over disk's unique ID?

Welp, me trying to be the devils advocate was a futile attempt.
