Do you need to enter a password for foreign bank card swiping?
Most foreign bank cards are signature cards, so you need to check your signature when you consume them. Passwords are only used for inquiry, online payment and ATM. In China, the Great Wall card of China Bank (except debit card) is also a seal card, and the seal is mainly checked when it is reused. Therefore, the Great Wall Card must be signed in person when handling the card. So, if you have a Great Wall card, please sign your gender name in person at the signature office, otherwise it is likely to cause trouble. But if there is a dispute, the bank will check the signature of the consumption bill and the signature of the bank card. If they are consistent, you can only admit that you are unlucky. If not, the responsibility shall be borne by the merchant. It is understood that the bank cards of other banks in China are all password cards.
