Therefore, if the amount of data to be encoded exceeds the storage capacity of a single QR code, multiple codes may be required.

2. Scanability issues

Another limitation of QR codes is their scanability. QR codes must be printed or displayed in a way that allows them to be easily scanned by a smartphone or QR code reader. Factors such as size, placement, and print quality can affect the scanability of QR codes. Small or distorted codes may be difficult to scan accurately, resulting in scanning errors or failure.

Furthermore, QR codes can only be scanned by devices equipped with a camera and a QR code scanning app. This means that users without a compatible device or app will not be able to scan QR codes, limiting their accessibility.

Note: It's important to keep in mind that QR codes are not universally understood or recognized by all individuals. Some users may not be familiar with the concept or may not know how to scan QR codes. Therefore, it's essential to provide clear instructions and guidance when using QR codes for communication or marketing purposes.

In conclusion, while QR codes offer a convenient and efficient way to store and share information, they do have certain limitations. Understanding these limitations and taking appropriate measures to address them can ensure the successful use of QR codes in various applications.
