there is a way to use a credit card called "payment without card", which is also called "payment without card". You only need to provide the card number and the last three codes on the back of the credit card to complete the payment. In addition, people's awareness of the confidentiality of CVV code is quite weak, which makes it available to criminals. Therefore, even if credit cards and passwords are strictly protected, there is a danger of being stolen.
Therefore, we must protect the credit card verification code carefully, so as not to let criminals take advantage of it.
three tricks keep an eye on the credit card
1. Cover the third yard with adhesive tape
Cover the last three yards with convenient adhesive tape, so that even if a "willing heart" gets the credit card or locks the card number in a short time, it may not succeed.
2. Don't let the credit card go away
When swiping a card, don't be afraid to take the trouble to give the credit card to the salesperson to settle the account, so as to prevent people with ulterior motives from taking the opportunity to obtain information about the credit card. The best way is not to let the credit card leave your sight.
3. Consumers' SMS and Times
Banking staff reminded that cardholders can set SMS reminders for credit cards, so that they can know the change of the amount in the card at the first time, and call the bank or the police immediately if there is any abnormality. In addition, users can also open the online payment function for credit cards when they need to shop online, cancel this function after completing the transaction, and reopen it when they need it next time.
