信用卡为什么签名？

信用卡作为一种便捷的支付工具，在现代社会中得到了广泛应用。然而，使用信用卡时需要签署名字，这似乎有些令人困惑。那么，信用卡为什么需要签名呢？

Secondly, the signature on the credit card can prevent fraudulent transactions. In the event that someone other than the true cardholder uses the card, the signature on the transaction slip will not match the signature on the back of the card, which will prompt the merchant to deny the transaction. This can help to reduce the risk of fraudulent transactions.英文翻译：
