问题 I am trying to generate AC manually, I have a tool to generate AC but I want to generate it by my own to understand the algorithm for the same. My calculation is fine for Discover card but it is failing for MasterCard. As per my understanding, data used to generate AC is depend on Tag 8C - CDOL1 which we provide to card with Gen AC command + AIP + ATC. AIP and ATC - accessed internally by ICC. Data used to generate AC is:- data part of Gen AC command + value of tag 82 + value of tag 9f36 + 80
