The fact that the QR code does not scan out does not mean that it is a fake. Currently the function of the QR code is limited to providing the place of production and price of the product, and can not indicate its authenticity. That is to say, the scanning out is not necessarily the real thing, such examples abound, the reason is that part of the producers can make their own two-dimensional code, in addition to the two-dimensional code can also be copied. The reason for this is that some producers can make their own QR codes, and QR codes can be replicated.
