Although some POS machines can check the balance, it is not recommended for users to use this method because it is easy to trigger the bank's risk control. Therefore, if users want to check the credit card balance, they can choose mobile banking, online banking, WeChat official account and so on.
Here are some ways to check the credit card balance, such as ATM, bank official website, customer service phone, electronic bill, etc.
Specific operational approaches and methods:
1. With your own credit card, insert the credit card into any ATM nearby, enter the password, and click the balance to query. The system window will display: balance and cash withdrawal balance.
2. Log in to official website Bank. You can choose to register for the first time, register your user name and password, and log in with your mobile phone number. After logging in, click "Bill Inquiry" to clearly see your credit card balance.
3. Call customer service: Call the customer service hotline or 400 toll-free number on the back of the credit card with your mobile phone or fixed line, check your balance on the manual line or make a voice broadcast according to the prompts on the bill checking line (you need to enter your own++and service password).
4. E-mail inquiry: When you apply for a credit card, you need to fill in your own e-mail bill, so you must remember your e-mail address, because there will be emails reminding you of the repayment amount and balance when you pay the bill. As long as it is under the bill, you can check it normally.
5. Online banking inquiry. Open your credit card, official website, and log in to your online banking. If there is no online banking, you can register a credit card to open online banking, and some banks need to go to the business hall outlets to open online banking. Select a credit card after logging in. Then select account information. You can see the amount of your credit card and the remaining amount you can use.
