英文:
Visa has no CVM List with contactless
问题
我们的收购方要求我们对达到x金额的所有交易进行CVM验证，但是当我们使用Visa卡进行非接触式交易时，没有CVM列表，因此3F是CVM结果，而CTQ是6800。大多数Visa卡是否都没有CVM列表是正常的？由于CTQ指示需要签名CVM，为什么CVM结果是3F？
英文:
Our acquirer required us to have CVM for any transactions that reached x amount, however when we do contactless with Visa cards there is no CVM List hence 3F is the CVM Result while CTQ is 6800. Is this normal for most if not all of Visa card to have empty CVM List? Since CTQ indicates that Signature CVM is required why does the CVM Result is 3F?
