One possibility is that the credit card applied for is a set of cards, that is, UnionPay cards plus foreign currency cards. UnionPay cards are suitable for domestic use, while foreign currency cards are suitable for foreign use. If the foreign currency card is of little use, you can choose to activate only UnionPay cards.

Another possibility is that the main card plus the secondary card. The main card is used by the applicant himself, and the auxiliary card is used by the immediate family members of the main card holder. If you don't pay attention to the secondary card option when applying for a credit card, you may get two cards, the main card and the secondary card. The secondary card also has a quota, and the quota of the secondary card can be freely specified, but it cannot exceed the quota of the main card.
