3. Dependence on internet connectivity: Since QR codes often link to online content, a stable internet connection is necessary for users to access the information or services associated with the QR code. In areas with poor or no internet connectivity, QR codes may not be a practical solution.

Key Distinctions between QR Codes and Barcodes:

In summary, the main distinctions between QR codes and barcodes can be summarized as follows:

• QR codes can store more data compared to barcodes.
• QR codes offer enhanced readability and compatibility with smartphones.
• QR codes have the ability to link directly to online content.
• QR codes require a scanning device and internet connectivity.
