Why is there a red bar when scanning the bar code, and the price is not displayed? Is it fake?

It's normal not to be scanned. It is impossible for every software service provider to contain all barcodes. So it's normal not to scan. Many people mistakenly think that scanning software is "omnipotent". It is not correct to regard these scanning software as software to identify the quality of goods. These softwares can only facilitate consumers to know the specific information of goods.
