The bar code is not clear enough or the mobile phone is not connected to the internet, which will cause the bar code not to be scanned. When we scan the bar code, we should first observe whether the bar code is clear enough, because the bar code is a lot of vertical lines, and the distance between them is very close. If the bar code is not clear enough because of humidity or water, it will not be scanned. In addition, if your mobile phone is not connected to the Internet, it is naturally impossible to scan bar codes. This situation may not be common among young people, but some elderly people will be confused, so don't blindly judge whether the goods are true or false just because they haven't scanned the barcode. First find out what caused the barcode not to be scanned.

The barcode mobile phone can scan, but the scanning gun can't scan out what is going on.
Towering and patient innocence
Industry answer
1, the function of reading this barcode is not enabled; 2. Barcode does not conform to the specifications, such as lack of necessary blank areas, low contrast between bar and space, and inappropriate length-width ratio between bar and space; 3. Under direct sunlight, the photosensitive device enters the saturation region; 4. The bar code is covered with transparent material, and the reflectivity is too high. Although the eyes can see the bar code, the reader has strict reading conditions and cannot read it; 5, hardware failure, contact your dealer for maintenance.

You can't scan the barcode with WeChat.
Odd in digital domain
Industry answer
You can't use WeChat to scan the barcode, dear, and the QR code of WeChat payment and collection can't be scanned either. The reason is as follows: 1. Maybe there is something wrong with the mobile phone camera that scans the code. First, check the phone, turn on the photo function, and see if it can be used normally and the photos are blurred. 2. Network problems. Network delay may cause the receipt and payment QR code not to be scanned. Check whether your mobile phone network is normal and can run normally. 3. The QR code has been damaged. Check the QR code for damage and stains. If there is, you can change the QR code. 1, first check the mobile phone and turn on the photo function to see if it can be used normally and the photos are blurred; 2. If the camera takes pictures normally, it means that there is no problem with the camera and the camera software, so this possibility is queued; 3. Next, check the WeChat software again. Open the web version of WeChat first, and try to scan the login QR code to see if you can log in to the computer normally. If everything is all right, skip to the last step. 4. If the WeChat login code can't be scanned, please open the setup application in your mobile phone, which contains WeChat, close it, and then reopen this software; 5. Try to shut down and restart. If not, click to enter the "Settings" of the mobile phone; 6. Then slide to the bottom in the "Settings" interface and click "More Settings"; 7. Click "More Settings" to enter "Permission Management"; 8. Find "WeChat" in "Rights Management" and click Enter; 9. Finally, set the "camera" permission; 10. If it can't be solved, restart the phone. If it can't be restarted, uninstall WeChat and reinstall it. I hope I can help you.

What is the reason for scanning the bar code but not coming out?
Electron 1 1
Praise god
Hello, dear, I'm glad to answer this question for you. 0 1, the bar code is not clear enough or the mobile phone is not connected to the internet, which will cause the bar code not to be scanned. 02, some foreign goods often can't be scanned, but they are not fakes. 03, if it is domestic, the bar code can't be scanned, which is quite probable.

The code scroll bar does not appear after scanning, but the results can be displayed. Why?

Hello, this may be because your mobile phone is stuck, and the results have been scanned without displaying the scroll bar, or the results are directly reflected too quickly, which does not affect your use.
