That becomes a huge amount data to track though if it's individual labeling. It'll start out ok but quickly get huge.

Also doing that requires a decent percentage of people to be actively scanning things, otherwise counterfeiters could just play the odds.

No, it's the same pattern as software CD-Keys and that's been working fine at scale for decades. You draw from a pool of unique, unpredictable codes based on a secret seed, and keep a tally of the number of claims over that code. The only difference here is that instead of the online service 'failing activation' for your software, it simply displays the number of activations to the end user. If 'this code has already been redeemed' comes up for your $2 ali express MOSFETs, you know you're dealing with a knock-off.

I'll partially concede this point - It's certainly a factor. However, if the down-stream effect is product returns, the middle man sellers are likely to take corrective action against the suppliers. I'm not convinced that this limitation of the proposed system will render it ineffective.

It's similar except you're not tracking one product with a few hundreds of thousands to a million or so at the largest scale to tracking many products with billions of copies sold. Just taking vitamins/nutritional supplements for example, last year that market sold 36.1 billion dollars in the US alone so ROM that's 1-3 billion codes to track. That gets whittled down pretty quickly by people who don't use the service but it's still a lot when you start adding other industries too.

The variety of products shouldn't matter though - You only need to know unique code and number of times redeemed. There is no need to track it back to an individual product.

For example, if you ship the unique codes with your products via a small card in the packaging, or a small product-neutral sticker applied to the outside, the end result is the same.

I hear you on the volume problem but I'm not sure it's a significant issue. A key/value store meets the need and will scale to billions while remaining space and compute efficient.
