After receiving a new card, check the name, expiration date and credit card type on the credit card in time.

2. Signature on the back of the card

Sign the signature strip on the back of the credit card as soon as possible, avoid using too neat signature when writing, use the signature method that best represents you, and don't alter it. Because when using the card, the merchant must check the signature on the cash withdrawal slip and the signature reserved on the back of the card before handling the payment procedure to ensure that the card is not fraudulently used.

If the unsigned card is lost, criminals can sign it with their own pens, which will cause great risks, and the issuing bank will not bear the losses for this risk.

Don't put the credit card with the password of your ID card, mobile phone or credit card. If you find that your credit card is lost or stolen, please call the customer service phone of the issuing bank immediately to report the loss.

4. Pay attention to avoid degaussing the magnetic stripe card.

Don't put the magnetic stripe credit card near any magnetic objects, and don't scratch it.

Don't place credit cards at will, don't expose the card number, expiration date, verification code and other information of credit cards to others, and don't lend the cards or the front and back copies of cards to others for use.

6. Cancel card cutting in time.

When a new credit card is issued due, please destroy the magnetic stripe of the old card in time.
