Consumption abroad mainly needs:
1, try to swipe your card by reading the IC chip, not by swiping the magnetic stripe.
2. Don't leave your sight when using the card.
3. Because you don't need a password for overseas credit card spending, you should reserve your signature on the back of the card.
4. Prevent losses. If it is lost, call the bank customer service phone to report the loss as soon as possible.
5. In some areas (mainly Southeast Asian countries), card theft and card cloning are common. If possible, reduce credit card spending outside banks and ATMs.
