I don't know which bank's credit card the owner applied for, but generally speaking the way to inquire about each bank's bill is pretty much the same, generally speaking there are these kinds of inquiries:

1. Counter inquiries, go to the bank to find a staff member, report the card number and ID card number inquiries can be.

2. Use the ATM machine query, the card will be inserted into the ATM machine inside the query.

3. Online banking inquiries, generally logging into the credit card center of each bank, logging into the personal system can be inquired.

4. Telephone inquiries, just call the bank's customer service hotline, you can find out.

5. If you want to know the details of your credit card spending, the most effective way is to get your credit card spending index, credit card transaction behavior, credit card spending characteristics and other information in such public platforms as Card Review.
