First, a copy of your ID card. If not, you can bring your household registration book.
Second, the bank's payroll records.
Third, the income tax withholding certificate under the landlord's name.
Fourth, the original work certificate issued by the employer or a copy of the work permit.
Prepare the above four items and you can apply for a credit card. If you have already bought a house, you can also bring a real estate license. I hope my answer can help the landlord!
