1. First of all, after applying for a credit card, you must remember to activate it first. Generally, just dial the activation number provided on the credit card and set the transaction password. Some banks may need us to go to the counter to activate.

2. If it is a previous credit card, offline shopping can only choose to enter the credit card transaction password on the pos machine of the merchant that supports credit cards. Of course, now, if the credit card micropayment function is enabled, you don't need to enter a password when swiping the card.

3. So what should I do if I want to spend money online with my credit card? In fact, it is not difficult. That is to bind our credit card and credit card payment function on our payment platform in advance.

4. For example, binding a credit card with Alipay is actually very simple. We open Alipay, click "Bank Card" on "My" personal homepage, then choose to add a bank card, and then follow the operation steps to enter relevant information as required. Refer to the following experience for the specific process.

5. After Alipay is bound to a credit card, when we use Alipay for online or offline payment, we can choose the payment method as credit card payment. Of course, the premise is that merchants support credit card payment.

6. Of course, in addition to Alipay, WeChat payment can also be tied to credit card payment. Refer to the following experience for specific binding methods. Binding a bank card is the same as a credit card.
