Do normal credit cards there not have cash back benefits? Do credit cards exist or because naturally they would charge you interest, do they not exist? It's interesting how there's a whole different ecosystem of apps in the part of the world that most of the world lives in.
Digital wallets must not be something akin to the Discover or Charles Schwab app on your phone, I recall hearing about them because there was an MLM ponzi scheme in Vietnam recognized last month where users would receive 80% cashback on paying bills and you'd receive more depending on how many friends you onboarded (with the app having a $100 minimum deposit to open an account). I don't know how that doesn't instantly seem too good to be true, then again I guess MoviePass seemed too good to be true.
