When applying for a credit card, you can provide as many financial certificates as possible, such as income certificate, bank deposit certificate, real estate certificate, automobile production certificate, etc. The bank will first evaluate the applicant's assets according to these certificates, and the bank's quota will vary from person to person. With these certificates, the number of places will naturally be higher. If the cardholder has a deposit in the bank, it will increase the possibility of approving the card and get a higher quota.
