Passport
Public, readable view of a batch: its origin, its journey, its certifications and the attached proofs. A passport creates no data — it makes already-signed data consultable. Three variants coexist: the consumer passport reached by QR, the Digital Product Passport in the ESPR sense, and the business-to-business delivery passport.
