Hello, the landlord, although it is said that having medical insurance and social security will get some extra points when applying for a credit card, having medical insurance and social security can not help the landlord apply for a credit card with a limit of 20 thousand. If the landlord wants to apply for a credit card with a limit of 20,000, he needs to prepare the following materials when applying:

First, the landlord's deposit certificate, because the credit card amount that the landlord wants to apply for is still relatively high, so it is best to prepare a deposit certificate with a higher share.

Second, the landlord's real estate license for free housing in this city, now the house price is so high, if it comes from owning his own house, it is also an economic proof.

Third, the landlord's salary card entry certificate for the last six months

It is also the driving license of the private car under the landlord's own name. The car price should be above150,000. This is the information I know. I hope my answer can help the landlord!
