Some cardholders will encounter repeated card swipes. For example, the cashier mistakenly thinks that the first card swiping operation is unsuccessful, and will immediately perform the second operation. In this case, you must ask the cashier to destroy the invalid consumption sign on the spot, or ask the merchant to cancel the repeated consumption transaction on the spot and ask for the cancellation voucher to avoid being deducted again. In addition, try not to let the card leave your sight when trading, so as not to be taken away by criminals and swiped repeatedly.

What if the credit card can't be swiped?

If you can't swipe your card, it may be that the magnetic stripe is damaged or the card limit is not enough. In order to prevent the magnetic stripe from being damaged, be careful not to put the credit card together with magnetic items such as mobile phones and handbags, and do not stick the magnetic stripes of two cards in opposite positions to avoid damaging the magnetic stripes. It's better to be open separately. If you find that the magnetic stripe of the credit card is damaged, please contact the issuing bank in time.

Make sure that your credit card balance is sufficient before spending a lot with it. If the credit limit is not enough, the cardholder with good credit can call the issuing bank to apply for a temporary increase in the credit limit, and the bank can increase the credit limit according to the credit status of the cardholder. In addition, in order to facilitate customers, some banks will give customers a certain amount of excess without special application. The cardholder can determine the consumption in advance.
