Precautions for swiping cards
Be sure to swipe your card during the normal business hours of the business. Don't always swipe your card in the early morning or midnight, and don't always spend money in the same business, let alone frequently swipe your card in large amounts, so as not to be suspected of cashing out by the bank. Don't empty or swipe your credit card frequently, otherwise the risk of credit card account will increase easily, and the bank may control the risk. If the credit card is overdrawn, it may also lead to the card being blocked.
