I have been traveling for some time now, so I can share my experience: Thailand - mainly cash, QR payment, bank transfer, when paying by card: +3% Cambodia – cash, cash, cash. Dollars and Riel. When paying by card: +3%-5% Laos – cash, cash, cash Malaysia – card and cash, sometimes QR payment, fast transfers, Indonesia – cash, QR codes, transfers, card in large stores, but the transaction takes a lot of time (they don't know how to use contactless payments) Palau – cash/card Taiwan – cash/card South Korea – cash and metro/city cards. Regular (non korean) cards only accepted at 7/11 Japan – mostly cash. Cards accepted at 7/11 stores and other large stores Poland – cashless everywhere. Cash is almost non-existent these days
