Sign on the back of the bank card as soon as possible.
When writing, you should avoid using too neat signature, and use the signature method that best represents you, and it must not be altered, because when using the card, the merchant must check the signatures on the purchase slip and cash withdrawal slip with the signatures reserved on the back of the card, and then go through the payment procedures to ensure that the card will not be 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.
3. Don't put the credit card magnetic stripe near any magnetic objects, and don't scratch it.
To ensure safety, please don't put the bank card with the password of ID card or credit card. If you find that your bank card is lost or stolen, please call the customer service phone of the issuing bank immediately to report the loss.
5. Don't place the bank card at will, and don't lend the card or the front and back copies of the card to others for use.
6. When the bank card expires and a new card is issued, please destroy the magnetic stripe of the old card in time.
7. Protect bank card information. Keep your own bank card purchase orders, statements and other documents properly, or dispose of them in time. Don't tell others the card number or reply to suspicious emails to ask for the card number, and don't leave card number information (card number, expiration date, etc. ) on computers used in public places. Check the bank card statement carefully. If you find an unknown transaction, please call the bank customer service immediately.
