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.
