The landlord must be cautious. Large credit cards must be handled through formal channels. As far as I know, the only online application is "I love cards". It is quite simple to apply for a credit card at this stage, but it is quite difficult to apply for a credit card with a higher amount. However, if you want to apply for a large credit card, you can try to start from the following aspects:

1. Have good consumption habits and be able to repay in full and on time;

2. Be able to provide relatively complete and weighty proof materials (such as income certificate, house property certificate, mortgage purchase certificate, work certificate, etc.). );

3. It is relatively easy to have a relatively stable work unit, if it is a state-owned enterprise or institution. However, if you already have one or more credit cards and have a good repayment record, you don't need to provide proof of income or assets, just provide a copy of the credit cards you already have and a basic application form.

In short, to apply for a large credit card, a good credit record and repayment record are the most critical! For the channel payment of large credit cards, once a refund is generated during the transaction, after the refund is successful, the money will be submitted to the bank within 2-5 working days (BOC: 6 working days) and returned to the credit card you paid.
