The signature on the back of visa card is in Chinese. It should be noted that the visa card is an international credit card, and the signature of the international credit card is the same as the signature column on the back of the international credit card. Cardholders should note that as long as the signature of a credit card needs to be handwritten, it must be in Chinese, and it does not distinguish between domestic and overseas.
Only when spending or pre-authorizing on overseas websites will the capitalization of the cardholder's name pinyin be involved.
