The magician shows to the audience a coloured thin cardboard that,  inside, contains another cardboard of different colour. In all there are  four cardboards held one inside the other. In the last cardboard the  magician inserts a white sheet of paper and closes all the cardboards  again as to create a single package. To finish, after a magic gesture,  he reopens all the cardboards and shows that on the last cardboard there  is a real banknote in place of the white sheet.
Other ideas: you can change a blank playing card into the card chosen by  the spectator. A sheet of paper will change into a business card. A 2  Euro coin will become a 20 Euro note.
