With the world working hard to get used to living with the new virus ‘COVID 19’, digital technologies have played an important role in advancing and streamlining essential up-to the minute communication in the form of Contact Tracing. For the success of contact tracing, the quick and effective use of QR codes has been vital in supporting the effort to try and stem the spread of the virus. Populations in many countries around the world have taken to using this convenient way of registering their location and movement throughout their daily life. This has directly helped reduce the human toll that could otherwise have been devastating. QR Codes (Quick Response) and the possibilities of their use will continue to support the health of general populations for years to come as this becomes a regular feature of our lives.
