Right. This is a far better (practical) solution. I only mentioned the object detection because detecting denominations of US currency was one of the ways the object recognition was demonstrated. Canadian currency has adopted large raised ink numbers which keeps the different bills the same size but it's probably more error prone than the AU solution.
