1. Check the card information

After applying for a new card, check the name, validity period and credit card type of the credit card in time.

2. Sign on the back of the card

Sign the signature on the back of the credit card as quickly as possible, do not use a neat signature when writing, use a signature that best represents yourself, and cannot alter. When using a credit card, the merchant must check the signature on the purchase form with the signature on the back of the card before processing the payment to ensure that the card is not used fraudulently. If a card without a signature is lost, criminals can sign it themselves, causing great risks. The card-issuing bank will not bear losses for such risks.

3. Separate card certificates

Do not use credit card and ID card, mobile phone or credit card password at the same time. If you find that your credit card has been stolen or stolen, please call the customer service number of the issuing bank immediately to report the loss. .

4. Be careful to prevent degaussing of magnetic stripe cards

Do not contact magnetic stripe credit cards with any magnetic objects, and do not scratch them.

5. Do not expose card information

Do not use credit cards casually, do not disclose credit card number, expiration date, verification code and other information to others, and do not change the card or the card number. Copies of the reverse side are available for loan.

6. Cancel and cut the card in time

When a new card is issued after the validity period of the credit card expires, the magnetic stripe of the old card must be destroyed in time.
