Biggest international and domestic payment card schemes in South Korea 2016-2022
Cards make up the vast majority of POS transactions in South Korea, with nearly six out of 10 payments being conducted with credit cards.
Neither Visa or Mastercard were the largest card brand in South Korea in 2021, due to the country's strong connection with card-based payments. This is exemplified in the source's reporting over time for the Asian country, where it tried in 2017 to map out several of the different schemes but to not do this again in following years.
