The basic requirements for each bank to apply for a credit card are the same. They must be at least 18 years old, with stable work income and good credit. Of course, it would be better if they had certain assets.
Summarized the card handling methods of the following banking channels:
First, to apply for a card through a bank outlet, you should bring your ID card and proof of work income (usually including: work permit, employment permit, salary card (preferably more than 3 months), tax bill, social security bill, provident fund bill for the last 3 months, etc. None of these are necessary, if you have any). If you can attach some financial certificates, such as real estate, automobile production, bank time deposit certificate, financial management, etc.
Second, there are banks that can handle cards through online channels (I use CCB, and his website is much more convenient than outlets), so the landlord may wish to try it.
