1. Applying for a second card will more or less refer to the approval result of the first card. Unless the applicant's credit conditions change greatly, such as bad credit or increased debt, it is easier to prove that the information provided is true and meet the credit card conditions.
2. Many people are white when they first apply for a card. After getting a card, they set up a credit record by using a credit card. Banks can evaluate cardholders' qualifications more comprehensively from their spending power and repayment ability. If they often use credit cards and can repay them on time, it shows that cardholders are trustworthy people and can easily gain the trust of banks.
3. If you apply for a second card in the same bank, although you also apply for a card online, you generally don't need to sign face to face after passing the examination, so it is relatively efficient to handle the card.
