Credit card theft liability:

According to the requirements of UnionPay, for credit cards without passwords, the acquiring merchants should strictly check whether the signature on the transaction voucher is consistent with the signature on the back of the credit card to check the identity of the cardholder.

According to reports, before becoming a special merchant, merchants must sign a "Code of Practice for Bank Card Business" with UnionPay and related banks, which also clearly stipulates that special merchants must check whether the cardholder's signature is consistent with the signature on the back of the bank card when accepting credit cards, otherwise it can be regarded as invalid.

Transaction Documents In addition, the Regulations on the Management of Bank Cards promulgated by the central bank also explicitly requires the acquiring merchants to bear the responsibility of checking the signature of the credit card, which means that once the credit card is stolen, if it is identified as a false signature through handwriting identification, the merchants will bear the main responsibility.
