What are the commodity anti-counterfeiting technologies on the market now?

Now I think the most commonly used basic security code is to give a string of numbers or two-dimensional code, and then you can know whether it is genuine or not by searching in official website. If it is genuine, he can naturally find the corresponding data, that is to say, if it is a pair of shoes, you can find out what color and shape your shoes will have this description, just like a computer phone. If this code is queried, it will have a related display. For example, if you scan the number 1 or QR code for a few minutes and seconds, then you can know whether what you bought is really new or genuine. I think this kind of defense is more reliable. After all, there is no third person between official website and the horse he bought, so it is quite reliable and easy to operate.
