How to display garbled code when printing and scanning nucleic acid sampling code with mobile phone?

What you want to ask is what happened to the sampling code and scanning code of your mobile phone? If so, the scanned QR code itself is an encrypted QR code, so the general code scanner may scan the code in disorder.

In our daily life, if the scanned code is garbled, we can try to scan other QR codes. If it can be scanned, it means another QR code. There may be two-dimensional code encryption, resulting in garbled code. Don't panic when the scanned code appears garbled. Ask relevant personnel in time. If someone else's code scanning function is normal, just check your mobile phone. If it is garbled, just notify the relevant management personnel.
