Chanel deserves this price. But this code scanning cannot definitely solve any problem. For example, get a real bottle, box, or can of fake perfume. It can be scanned out as well. Nowadays, the technology of counterfeiting is amazing. Some perfumes are so well imitated that they look just like the real thing. Old perfume players will be fooled. Not long ago, my friend bought a bottle of Chanel Encounter through her WeChat. It was so real, but unfortunately, That's false.
Do you suspect that there is something wrong with the goods your friend sells? Then this is difficult to handle. If you two usually have a good relationship, there should be no problem. If it works well, don't worry about it. To put it bluntly, perfume is just that, the bottle looks good, smells good, and you are happy to use it. Some words, even if said tentatively, can hurt feelings. Friends need trust.
But to put it more vaguely, if you just have a normal friendship and he is a micro businessman, then it is entirely possible for him to trick you.
