Hello! The friend on the first floor is right! According to the fee, it must be used by myself, and the cardholder's reserved signature must be signed! Card issuers and merchants will keep your signed name and original handwriting just like this without showing it! But China's financial system has not yet been in line with international standards! Only by entering the password! But signature is a must! This is indeed one! But you don't have to sign what you said! This is impossible! No matter at home or abroad! If you don't sign it, you can totally repudiate it! I have come across this case! After a customer in Guangdong paid the bill by credit card, the waiter forgot to sign it for the customer, and the issuing bank refused to accept the transaction! He obviously spent money here! Why don't you deduct the money from me? There is no customer's signature on the bank record! And the customer doesn't admit that he is spending money here! Therefore, the bar can only eat Huang Lian in silence, and it is hard to say that it is necessary to sign a name! This is.
