pack coding which enables access to the same information held on a secure database.
(This latter solution overcomes some of the concerns about privacy where the encoded

These serve a number of distinct functions:
(a) Tracking an item through the supply chain, to each point where there is the facility

(b) Providing traceability on the history of any item (electronic pedigree), subject to
limitation of number of control points.
(c) Enable authentication of the data at any time, and by implication, of the pack or unit
on which it is applied.
