Those heading overseas this summer are reminded that credit cards lost or illegally copied should be reported to the local police and frozen immediately.
That's according to Korea's Financial Supervisory Service, which says cases of credit card theft tend to surge in the third quarter of the year.
The agency suggests that vacationers reduce their credit card limits, avoid ATMs in secluded areas and keep receipts for every transaction.
They should also avoid using dynamic currency conversion, which makes travelers pay in Korean currency while abroad and charges extra transaction fees.
If a card is used without authorization, make sure to get a police report from the local authorities and submit it to your card company.
