I don’t need to open another account, fumble with one-more-app or anything. Also apple-pay appears to mask my CC/DC number as well, so better safety.
I want it everywhere badly in west as well as east and middle(-east).
I am familiar with UPI and few similar things in other neighbouring countries(looks like every SEA country has its own entirely different version of it and some country has almost 4-6 competing copy-cats!).
