Credit card swiping and precautions:

First, tear the wrong order on the spot. If there is an error or cancellation of the transaction, the wrong order must be torn on the spot; If the merchant uses the computer online credit card terminal, please ask the salesperson to open a Zhang Chong bill to offset the original transaction, and then conduct the transaction again, or ask the merchant for a refund voucher. In addition, the signed bill should be properly kept for future verification and to avoid being forged.

Second, don't sign the bill with blank or incomplete amount. When purchasing, the merchant will ask you to sign the transaction documents. Pay attention to whether the recorded amount is correct before signing, and sign it only after it is confirmed. The name on the signature should match the name and handwriting on the credit card.

Third, please confirm whether there are two overlapping bills and try not to let the cards out of sight.

4. When spending by credit card in the same store, it is suggested to select all the goods to be purchased first, and then swipe the card at one time. It is best not to swipe your card in the same store more than twice in a row, which may lead to the acquiring bank refusing to trade.

5. For spending abroad, there are three columns on the credit card-Base Amount, tip and Total amount. You can fill in the tip amount in the "tip" column, add it up and fill in the "total amount" column, and finally sign the bill.

It should be noted that the total amount must be calculated correctly because the payment is based on the total amount. Write one more zero, and the tip will be more.

6. When you swipe your card abroad, pay attention to the currency of the purchase order. For example, the difference between the small yen 1 yuan and the dollar 1 yuan is 108,000 miles.

There are four dates to keep in mind when using credit cards. They are:

1, trading day. Refers to the date when the credit card is actually spent, withdrawn or transferred.

2. Bank bookkeeping date. Refers to the date when the bank records the transaction in its account. It should be noted that the transaction date in the bill refers to the day when the card is swiped, and the bill date is different. Because it takes a while for the credit card information of the store to reach the bank, it may be one day or two or three days.

3. Bookkeeping date. Refers to the date when the bank "calculates the general ledger" for credit card transactions every month.

4. Due repayment date. Repayment must be made before this date. If this period is exceeded, interest and other related expenses will be paid for the money owed to the bank within this period.

Only by figuring out what these four dates mean can we make full use of the interest-free overdraft function of credit cards.
