如何找到信用卡的安全码

by Estelle

信用卡上的安全码是一串特定的数字,如果您想在网上购物,就需要用到它。

信用卡上的安全码:如何找到它

安全码是一个三到四位数的数字。它通常位于信用卡背面。该代码也称为卡验证号码,缩写为CVV,用于卡代码验证。根据供应商的不同,它也可能缩写为CVV2、CCV、CVN、CVC(用于万事达卡)、CSC或CSC。

  • 此安全功能无法通过机器读取,可防止信用卡被滥用。
  • 如果您想进行远程支付,例如支付网上购物的费用或预订旅行,则需要安全码才能通过信用卡支付完成支付流程。
  • 使用万事达卡和维萨卡,您可以在信用卡背面找到三位数的验证码。它位于签名栏上方、旁边或下方。
  • 使用美国运通卡时,安全码为四位数字。第二个特点是安全码位于信用卡正面。

信用卡号码与安全码

信用卡号码和安全码或校验码是两个完全不同的概念。

  • 信用卡号码有12到16位数字。几乎所有信用卡上的数字都是压印的。一些公司,如巴克莱银行,已经开发出新的信用卡。在这里,16位数字现在印在背面,不再是压印的。
  • 而卡验证号码只有三到四位数字,且不采用浮雕设计。几乎所有信用卡的背面签名栏附近都有这个号码,通常以斜体字显示。
  • 一些较新的信用卡公司将卡验证号码印在信用卡号码下方。有效期也印在旁边。
  • 所有信用卡都有一个共同点,即信用卡号码和安全码或验证号码之间没有关联。
