If you are a card of China Merchants Bank, you can distinguish it according to the following information:

1. The first six digits of the card number, debit cards and credit cards are not used. Please consult customer service in detail and provide the first six digits of the card number to judge;

2. The debit card of our bank will be marked with "All-in-One Card" and the credit card will be marked with "Credit Card".
