In particular, the new bills would have an miniature image of Mikky Mouse's head. Also the new banknotes will have miniature lettering, that cannot be seen without a magnifying device, and which will look like a simple line when photocopied. We will also use a special ink, which cannot be manufactured without the proper equipment and the knowledge of the secret formula. Another feature that is used in banknotes of may countries is watermarks, that can be seen if the bill is held to the light. On our bills we will have a watermark containing the image of the flag of the United States.
Holograms are virtually impossible to create without sophisticated equipment.
If any of these features is missing or corrupted, one can safely conclude that the bill is fake.
