If you want to increase your credit limit at the same time, please provide new financial proof documents. 1. Log in to the credit card website/, fill in and download the printed application form online (don’t forget to sign), and mail it directly to the credit card center together with the new application information; (cards applied through shortcuts do not need to submit information, just submit it directly online) 2 , Go to any business outlet of China Merchants Bank to apply in person.
