If we want to solve the invalid transaction, we must find out the reason. If you can't find the reason, you can also call the issuing bank and continue to use the credit card after the solution. Another possibility is that the credit card shows invalid transactions, the credit card is demagnetized, and it is impossible to swipe the card on the POS. You can try to tie the card or scan the code to pay. If it is frozen due to overdue repayment, the cardholder needs to pay off the arrears first, and then call the issuing bank to see if the credit card can be restored to normal.

Credit card cash withdrawal and credit card consumption have the following differences:

1. Credit card limit is different: credit card consumption has no limit within the available credit card limit; The withdrawal amount of each credit card is generally 30% or 50% of the fixed credit card amount.

2. Different interest-free periods: credit cards have a certain interest-free period, and you can enjoy the interest-free period before repayment; There is no interest-free period for credit card withdrawal. From the date of withdrawal, interest shall be charged at 0.05% of the withdrawal amount every day.

3. Different points rules: credit card consumption can accumulate points; Generally speaking, credit card withdrawals cannot be counted as points.

Credit card withdrawal is best paid off on the day of billing.

In addition to overdraft consumption, credit cards can also be withdrawn, no matter which way they are used.

We know that credit card withdrawal will also be paid on the day of the bill. According to conventional thinking, you only need to pay it back on the repayment date. This is true, but it may not be rewarded. After all, the credit card will involve an interest, and the daily interest will be five ten thousandths from the date of withdrawal to the date of bill. If repayment is made on the repayment date, the interest generated from the bookkeeping date to the repayment date will be calculated from the next bookkeeping date.

In addition, the order of credit card repayment is to deduct interest first, and then deduct principal. Many people originally planned to pay off the principal before paying off the interest. Unexpectedly, the interest was deducted first, and the remaining money was definitely not enough to repay the principal. If the principal is not paid off, it will continue to generate interest and compound interest on a monthly basis, which is obviously not cost-effective.

Therefore, it is best to withdraw cash with a credit card on the day of the bill, and repay according to the amount owed, without delaying it to the repayment date. Of course, it can also be returned on the same day, but there is a one-day interest and withdrawal fee.

In short, credit card withdrawal and repayment should not be delayed for too long, otherwise it will generate a lot of interest.
