월드 베스트 호텔 보러가기
Brooke Ferencsik, of travel site TripAdvisor, suggested that consumers keep a watchful eye on their accounts both during and after traveling.
"Credit card theft can happen anywhere. It can happen at a restaurant. It can happen at your hometown supermarket," Ferencsik said. "It really seems like this is a bit of a random incident."
His tips for travelers: keep the phone number of your credit card company on hand and review your online statement every once in a while during your trip.
He also noted that credit cards offer 100 protection from theft, as long as you report your loss in a timely manner.
"Credit cards still remain the most convenient method of payment for most travelers," Ferencsik said, "and it's often safer than carrying around cash."
