I have an idea to make bank notes for visually impaired people by punching certain pattern of holes on the bank notes. Hole can be any shape. Advantage: (1)Can be easily distinguished, even with circulated and worn out bank notes. (2)Can be applied to old notes and old design.

• 
  "Bank note 1"
• 
  "Bank note 5"
• 
  "Bank note 10"
• 
  "Bank note 20"
• 
  "Bank note 50"
• 
  "Bank note 100"
