It is not possible to have public as aware as perceived to receive the information through the innovative sources.

Limit the reception audience

To access the information using QR codes we need to connect the devices with the internet that requires a little maintenance. Not everyone is available with an internet connection or free wifi all the time to access the information. So, being friendly to this technology might cost much to the people in general.


QR codes seem to be an advanced mode of advertising and marketing that bring innovation to the field. On the other hand, advancement comes with some limitations that require a solution. A little more awareness and technology friendly attitude will bring real change in the situation.
