Hello, applying for a credit card through a credit card intermediary is not a formal channel for applying for a credit card, and is illegal to a certain extent.
At present, applications for credit cards launched by major banks can be processed through the corresponding formal branches of the bank, or applications can be made through various methods such as downloading application forms online, direct mailing, etc. As long as you fill out the application form as required and provide your true credit information, you can apply for a credit card within the bank's credit policy without paying any application fees.
Be sure to avoid trying to deceive the bank by making false claims. Instead, you will be used by others to deceive you, and inadvertently leave a stain on your credit record. It is recommended that you apply for a credit card through formal channels and beware of being deceived.
