It's crucial to test QR codes before publishing them to ensure they work properly. Mistakes can happen during the generation process, and a faulty QR code can lead to a frustrating experience for users. Make sure to scan the QR code with different devices and apps to ensure compatibility.

Not Optimizing QR Codes for Different Scanning Conditions

QR codes may not be scannable under certain conditions, such as low lighting or small printing sizes. It's essential to optimize your QR codes to be easily scannable in various conditions. Make sure there is enough contrast between the QR code and the background, and avoid using small fonts or images that can distort the QR code.

In conclusion, when using QR codes, it's important to provide clear instructions, have a purpose for using them, test them before publishing, and optimize them for different scanning conditions. By avoiding these common mistakes, you can ensure that your QR codes effectively deliver the intended information and provide a positive user experience.
