2. Align the view frame with the bar code on the commodity for scanning;
3. If the scan code is successful, you can identify the information and judge whether something is true or false according to the content displayed by the scan code;
4. You can also log in to China commodity information service platform or anti-counterfeiting inquiry center and enter the barcode for verification.
Barcodes are generally used for commodity inventory and trading. You can find relevant information when you enter a commodity, but you can't find it without entering it.
Extended data:
Two-dimensional code is also called two-dimensional bar code, and the common two-dimensional code is QRCode, which is QuickResponse. It is a very popular coding method in mobile devices in recent years, which can store more information and represent more data types than traditional bar codes.
Function:
Information acquisition (business card, map, WIFI password, data);
Website jump (jump to Weibo, mobile website, website);
Advertising push (users scan the code to directly browse the video and audio advertisements pushed by merchants);
Mobile phone e-commerce (user scanning code, mobile phone direct purchase order);
Safety traceability (users can scan the code to see the origin; At the same time, the background can obtain the final consumption location);
Preferential promotion (users scan code, download electronic coupons, draw);
Member management (get e-member information and VIP service on the user's mobile phone);
Mobile payment (scan the QR code of the goods and complete the payment through the mobile phone channel provided by the bank or the third party payment).
You can see the name, place of origin, manufacturer and price of a product by scanning the code with mobile phone software, but some product information is updated quickly, the database may not have relevant information, and the software upgrade is not timely, which will lead to the inability to scan the product information, but it cannot be used as a basis for distinguishing between true and false. Scanning bar code is not used as the basis for judging the authenticity of goods, but should be inspected according to the relevant incoming inspection system.
The bar code of goods can be copied. If the barcode or QR code of a regular commodity is sprayed on fake and shoddy products, it is not credible to distinguish authenticity by scanning the code.
