Overseas card spending by South Koreans posted double-digit growth for the second straight year in 2018 due to a larger number of outbound travelers and a weaker US dollar, according to the Bank of Korea.

Koreans made $19.22 billion worth of card payments abroad last year, up 12.1 percent from a year earlier, according to the data from the central bank.

Overseas card spending includes purchases made with debit and direct payment cards, in addition to credit cards.
