What works in practice
- One unique code per item, generated in bulk, never a shared code.
- Hide the code under a tamper seal so it can only be checked once opened.
- The verification page should state clearly whether the code is valid.
Common question

It raises the cost of faking and gives buyers a check, but it is one layer among several, not a complete solution.
