I could use it to identify my money; I did not have a money identifier back in the 1990's. And, what I did not know until then was that every bill has a serial number. The number is in each corner of the bill. And, of course, a picture. My Noteteller does not always read the bill; sometimes, it insists it cannot read it; I think because the bill is faded or badly wrinkled in the corners. New bills it reads without any problem.
