It has everything to do with credit cards if you understand what the parent comment is saying. Credit card allowed people to use something else other than cash when internet banking/digital payments wasn't available and smartphones were not a thing. Their entire society adopted credit cards as a very normal way of payment even for everyday stuff since it offers convinence over cash and rewards.
Yes India got credit cards but it was not widespread and people did not use it as a daily thing since most stores/outlets did not have the card swiping system. UPI solved this problem very well since you just need a QR code and a valid bank account and no transaction charges making it perfect for day to day spending.
We got digital payments and smartphones together. But in the US for example, credit cards came much earlier and were able to capitalize very well since there wasn't a lot of the technology at that time which we take for granted today.
