It is easy to apply for a credit card as long as you are over 18 years old, have a proper job and have a stable income. The general information channel is: apply for a credit card online, or apply at a bank outlet. Of course, if there is a salesman in the supermarket or on the roadside, you can also apply. However, compared with the above two methods, the application speed of the salesman is the slowest, and there is no way to guarantee the security. It is recommended to apply for a credit card at CITIC Bank official website. Under normal circumstances, if you apply online, the head office of the bank will receive your information soon, and the speed of card approval will be faster, and the speed of salesman filling out the form will be twice as fast.
