CVV 的含义:简单解释卡片验证码

by Corinna

您应该知道 CVV 的含义,因为卡片验证码是信用卡和借记卡的一个重要安全方面。

CVV的含义:数字背后是什么。

CVV是卡片验证值(Card Verification Value)的缩写。它是大多数信用卡和借记卡背面的三位数字。美国运通卡是个例外。这里的卡验证码位于正面,由四位数字组成。

  • 引入 CVV 是为了加强对欺诈行为的保护。这尤其适用于不出示实体卡的交易,如网上购物。
  • 当您在网上购物或支付服务费用时,通常会要求您输入卡号、有效期和 CVV。输入 CVV 可确保您确实拥有该卡,而不仅仅是知道卡号和有效期。
  • 由于 CVV 不会出现在收据或其他文件上,也不会以磁性方式存储或存储在卡的芯片上,因此它为防止银行卡欺诈提供了额外的保护。
  • 重要:切勿在电子邮件或电话中透露您的 CVV。在网上使用您的银行卡信息时,只使用安全可信的网站。
