If you need to enter a password in China, it means that the dual-currency card uses "UnionPay" POS to swipe the card, which is the verification secret (unless you don't need to enter the password yourself, such as China Merchants Bank, Bank of China, ICBC and other credit cards, you can set the transaction signature or signature+password). When you arrive in Britain, you don't need to enter a password when you swipe your card in a physical store with VISA POS. Sign it. Since you issued the card in China and signed it in Chinese characters, there is generally no need to look up the name. But if you make a large transaction or use it in a duty-free shop, you need to check whether it is you (ask for a photo ID card, such as a passport, etc. ). So you can use it now, and it's not a big problem (for example, in a supermarket, etc.). ), but you'd better ask your father to get you a supplementary card. The amount and type of the supplementary card are the same as those of the main card, but it is under your name (your name pinyin is printed on the card surface), and it will be mailed or sent to you later ~
