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?
First, please read kernel C-3 documentation available on EMVCo website to understand how to interact with the kernel, how your payment application should behave and how to configure the parameters to meet your acquirer requirements.
CVMR, same as TVR are not used during these contactless transactions that are using a different flow than contact. For more details regarding this brand regulations, refer to their documentation like VCPS and TADG.
