網(wǎng)申時如何填visa信用卡上的security code

在遇到用visa支付時，大家可能遇到過要輸入credit card security code

在簽名的那一條上，應(yīng)該印有一個三位數(shù)的數(shù)字。不是卡號的后三位，既然叫security number,就是為了保險安全使用visa卡啊，銀行是不可能知道這個信息的，就是知道也不可能透露。

注1：工行規(guī)定，登陸境外銀行網(wǎng)上劃賬，需要開通授權(quán)功能的。

英文原文：

What is the Security Code?

It is an important new Internet security feature that now appears on the back of most Visa/MasterCard and Discover cards, and on the front of American Express cards. This new code is a three or four-digit number which provides a cryptographic check of the information embossed on the card.

The security code helps validate that the customer placing the online order actually has the credit card in his/her possession, and that the credit/debit card account is legitimate.
