it won't disappear. It is necessary to settle accounts in two currencies! First of all, you have to understand the concept of dual-currency card. Dual-currency card refers to a bank card issued by many domestic banks with two currency settlement accounts, namely RMB and foreign currency accounts, and with the logo of UnionPay and another international bank card organization. Secondly, a card with two logos is not a dual-currency card. In fact, there is no such thing as a dual-currency card in the world. This name is only available in China. If your card has any logo of the card organization, it can be used in this area, and it is generally settled in the currency of the receiving place. Due to the characteristics of China, people who have UnionPay and VISA (or other) logos often think that this is a dual-currency card. The cards with UnionPay and VISA logos issued by China should be called dual-label cards (two card organization logos), and dual-label cards and dual-currency cards are two concepts. UnionPay and VISA dual-label cards represent the significance that this card can be accepted by merchants or terminals in UnionPay network and VISA network. It doesn't mean that your card has two logos, UnionPay and VISA. It is a dual-currency card.
