I don't make holograms. Is this still for me?
Yes, and the two things AVRA actually sells do not come from a hologram. Batch Activation is a rule in a database — codes are dead until you activate the batch after QC — and it works identically on foil, board, film and kraft. Dual Code needs somewhere on the pack to hide the second code, which is a question about the format, not about who made it. See What the code sits on above for what each substrate can carry.
What a hologram adds is tamper-evidence and hard-to-source physical stock, and it is still the best commonly available answer to both. If you do not make one, the honest options are a destructible face stock, a VOID-release adhesive, a perforated band or a tamper-evident seal — or telling the brand plainly that the pack carries none, which is better than implying it does.
