If you report the loss in time, China Merchants Bank now has a "lost card protection" ... that is, it will be pushed forward for 48 hours from the time you report the loss, and all transactions that are not your own (subject to your signature) will be borne by China Merchants Bank within these 48 hours. ...
If you don't report the loss in time, you must call China Merchants Bank to handle the problematic transaction. Because it's not your own transaction, the POS signature is different from the signature on the back of your card ... which can be determined by handwriting identification ... and your card is lost, so you can't check the signature. This can only be done by reporting the case, trying to get your card back through the police ... or going to the court for handwriting identification.
Don't worry, as long as it's not your own consumption, the money will definitely be recovered ... it's only a matter of time.
In addition ... your supplementary statement is wrong ... Lonely Overlord probably doesn't know much about credit cards, or doesn't distinguish between credit cards and ordinary savings cards ... But at present, among all banks that issue credit cards in China, except China Merchants Bank/Bank of China (except city cards), other credit cards can pass signature+password authentication ... (Payment must be made in China and settled through UnionPay channel).
Finally, the banking law stipulates that when a cashier swipes a credit card (or debit card) in the cashier's process, he must check whether the pinyin name at the bottom of the front of the card is consistent with the Chinese characters on the back signature strip, and the back signature strip must be signed to be valid .. The cashier must also check whether the POS signature is consistent with the signature on the back of the card. ...
If the signature is inconsistent but the money is deducted, all losses will be paid by the merchant. ...
