Hello, landlord! It depends on which bank you want to apply for a credit card. Some salesmen can handle it at home. But the door-to-door application requires the landlord to apply online in advance. For example, after the online application of ICBC and China Construction Bank, staff will come to collect the application materials. If the landlord is satisfied, you can apply for credit cards from these two banks. I wonder if the landlord understood what I said. I hope my answer can help the landlord!
