Digital Stamp is a small designed mark printed on a document. The mark holds fifteen characters. A phone camera reads it, Decode confirms the person has the right to open it and for how long, and the document is regenerated or verified only then.
Every issuer designs its own stamp
- Your colours, your shape, your identity.
- A different code on every document.
- IDs, passports, visas, permits and certificates.

The same stamp on a product
In product mode, one stamp on the product brings up the current manual, label or guide with one scan. Where every unit shares one manual, a plain QR code may do the job more cheaply; the stamp is for marks that must be branded, unique per unit, or checked by Decode.

Which document types are in scope for the first release is still being decided.
