If you want to exchange cards, just remember the repayment date of each card. Before the repayment date, you can use one of them to transfer the amount to repay other cards. After paying off one card before paying off another card, the operation must be completed before the repayment date. First choose a card with a close repayment date to repay.

For example, I have three credit cards from Guangda Bank, China Construction Bank and Guangfa. The repayment dates are the 14th, 18th and 23rd respectively. Today is the 14th. Since the repayment date of Everbright is approaching, we should start by paying back Everbright, pour out the amounts from other cards and pay back, and then pay back Jianshe and Guangfa in sequence. Just make the repayments as per each card's bill.

It should be noted that during the operation, try not to clear every card, and try to keep a quota of more than 20. One card should have to be swiped out multiple times before returning other cards. The amount of each card swipe shall not exceed 50% of the total amount to avoid risk control.

Card friends can effectively extend the repayment period of their credit cards by doing this. However, the money after overdraft must be paid back, so you must spend rationally and try to control it within your repayment ability

What is the principle of credit card reversal?

When the credit card bill comes out, you only need to pay off the balance between the repayment dates without incurring overdue fees or other charges. So the first reaction of many people is that they don’t have the money to pay it off in one go. In fact, many of us operate like this: the 1st is the bill date, and the 16th is the final repayment date. Then, starting from the 2nd, I will first pay back 5,000 and then cash it out; I will pay another 5,000 on the 3rd and then cash it out. At this time, your 100,000 bill only has 90,000 left, because the bank calculates the repayment based on the cumulative repayment amount of this cycle, rather than requiring you to repay it all at once, which gives us a lot of room to operate. Pay off all debt with the minimum amount.

Things you need to pay attention to when transferring cards:

1. When the funds are still there, do not withdraw them immediately. It is best to refresh the page every 2 hours or more, which is suitable for small and diversified businesses.

2. Merchants usually use: catering, department stores, beauty, hotels, bars, entertainment, clothing, etc., but never use building materials, wholesale, jewelry, auto parts. The risks of these industries are controlled by banks. You're operating card reversals, so it's easy to reduce the amount of risk control.

3. If the billing dates between multiple cards are close, call customer service to apply to modify the billing date. First ensure the fund chain, and then consider whether the impact will affect withdrawals. Seven days between settlement dates is ideal.

4. Card merchants choose standard rates. If there are additional fees, hundreds of cards must be swiped every year, which will add hundreds of thousands in fees.
