Even though I have only had limited travel experiences in Asian countries like China, Taiwan, Japan and Korea, it is evident that there are plenty of cases where QR code is much more pervasive in applications like transport and retail compared to western countries like US, Australia and UK.

Is there any specific reason for these differences, at least when it comes to anything that can be explained by technology and business constraints rather than cultural differences? And if it is really an issue of cultural differences, what is the reason for it and how does it apply in countries where there is a good mix of eastern and western cultures like Singapore and Hong Kong?

UPDATE: Due to the measures taken by the government authorities in countries like Australia to introduce mandatory roll-out of digital contact tracing processes, QR Codes are actually becoming part of the 'normal' daily life. Whether this spreads to other aspects of online and social activities remains to be seen.

  • Just to observe that going by past QR questions this difference in adoption has been going a long time.

  • @PhillipW that's true, but I can't say for other countries although where I live in Australia this has seen such a dramatic change during the recent pandemic that it is almost the only single driver that I have seen for its adoption.

    Super app is widely used in Asian countries compared to Western. The adoption of QR scanning by these super apps eases the implementation: customers use a super app to scan the QR code for various services under the umbrella.

You will see more QR codes wherever marketing and advertising people think the population has more access to QR code readers (basically any modern mobile phone). So it might be easier to conclude that you will see more QR codes in urban or touristy places.

Since you've only traveled to touristy places, you might conclude that the whole country is like that.
