A few days ago, I applied for a VISA Platinum Dual Currency V master approval and passed the CCB Platinum Dual Currency Credit Card. The limit is generally 50,000 yuan, but it is shared with your gold card. That is to say, the 30,000 yuan of your gold card is within the 5,000 yuan limit of the platinum card. The maximum consumption of the platinum card is 5,000 yuan, and the maximum consumption of the gold card is 3,000 yuan. If the platinum card consumes 5,000 yuan, the gold card cannot consume any more. If the gold card consumes 3,000 yuan, the platinum card will consume 3,000 yuan. You can spend up to 20,000 yuan more.
