When swiping a credit card abroad, many places will require the person swiping the card to show their passport, and they will check whether the name on the card is consistent with the passport. Therefore, it is generally unlikely to swipe someone else's credit card. Credit card ownership belongs to the card issuer, and the cardholder is only the user. According to the credit card agreement, no one other than the cardholder can legally use the credit card. It is illegal to use someone else's credit card. If the store clerk checks the ID and finds that the card user is different from the cardholder, he can call the police. It is recommended that you bring a few more cards of your own before going abroad. If the limit is not enough, you can call customer service to apply for a temporary limit increase.
