Domestic banks' credit cards basically adopt centralized management mode, that is, banks first set up their own credit card centers in a certain city. If residents of other cities in China apply for a credit card, they need to collect the application form at the card center first, which will take several days. After the credit card center receives the credit card application materials from various cities, it takes 15 days to review and file them. Then there is making cards. Due to the high value of business card printing equipment, it is basically made by credit card centers of domestic banks. This process usually takes two days. The last step is to send the card to the cardholder by registered mail, which usually takes 7 days-15 days. Counting the possible delays between various links, it is normal to get the card in 40 days.
Therefore, the case can be filed about half a month after the preliminary examination.
