The premise is that the credit card and debit card must be from the same bank. There are two ways, one is to go to the bank branch to apply. The second is to open online banking (any debit card or credit card is enough) and then operate it yourself on online banking.

But in fact, there is no need to bundle them together. The only purpose of bundling them together is that when the credit card repayment time comes, the bank will automatically deduct the money from your savings card to the credit card. Instead of doing this, you might as well just swipe your debit card. This only works for those who often forget to repay their loans.

The benefits of swiping credit cards are actually not that many. You can exchange some small points for small things. Even these points require you to spend a lot of money to get them (now many debit cards also have card swiping points), and the longest is only 56. Days of interest-free time have to be paid back every month. Very troublesome.

The most troublesome thing is that when you apply, you must choose between "minimum repayment" or "full repayment". If you choose to repay in full, every month, you will pay How much credit card you have will be deducted from your savings card, but if you choose the lowest one, there will definitely be interest. But regardless of the minimum amount or the full amount, if there is not enough money on your savings card, the repayment will fail. The same results in overdue. Incurring interest and late fees and affecting credit, etc. You still need to make sure you have enough money on your savings card.

It is very convenient for you to open online banking with your savings card and transfer funds online yourself.
