### Banknote Signed Certificate Proposal (Spec, Main Page, Source Code)

#### Design Restrictions

- QR must fit a 10x10mm area on a bank note
- QR must contain all the fields of the note
- Must be readable by a regular phone

#### Benefits

- Counterfeiters can only duplicate notes (changing serial number breaks the signature)
- Duplicated serial # are easier to track down
- Build a "Revocation List" for individual numbers
