In order to facilitate the binding of debit card and credit card, the repayment money will be stored in this debit card and automatically deducted on the debit day of the credit card to prevent the credit card from being overdue. This is also a way for banks to increase the amount of cards issued and deposits.

Another possibility is that the main card plus the secondary card. The main card is used by the applicant himself, and the auxiliary card is used by the immediate family members of the main card holder. If you don't pay attention to the secondary card option when applying for a credit card, you may get two cards, the main card and the secondary card. The secondary card also has a quota, and the quota of the secondary card can be freely specified, but it cannot exceed the quota of the main card.

Matters needing attention in handling credit cards

Although the current threshold for handling credit cards is very low, it does not mean that there is no threshold. For the four major banks, their risk control system is relatively perfect and there are many customer groups. If your qualifications (whether you have a stable job and income, apply for bank flow, etc.). ) are not very good, it is recommended not to apply for credit cards of the four major banks, which may be rejected.

It should be noted that most banks have benefits and activities in credit cards, such as exchanging consumption points for gifts, or spending on various discount days, and cooperative businesses have consumption benefits and so on. Banks with many benefits have many consumer concessions, many kinds of goods exchanged for points and many incentives. These are hidden benefits, accumulated all the year round, and also a lot of wealth.
