大家知不知道什么是银行卡的CV2号码?

* Your card’s CV2 number is the rightmost three digits printed on the signature strip. We do not store your CV2 number, but use it to perform a security check when you change your credit/debit card details in any way.

这个CV2是什么号码?去银行能问到吗?ABN的卡

还有就是 Issue number 是什么?

u can ask the bank or check your contract of ABN.

CV2就是卡背面7位数字的后3位，很容易找的。
