问题描述
我现在正在运行 MasterCard M-TIP 测试用例，但无法通过“该卡以 TC 响应第二代 AC”的要求之一.
如果有人可以提供有关正在发生的事情或出了什么问题的见解，我将不胜感激。我附上了 iso8583 日志 和第一次和第二次生成 AC 的测试日志 以及参考。

从 ISO 日志中，您可以看到主机实际上已批准交易，但我不明白为什么该卡以 AAC 而不是 TC 响应。
解决方法
您的主机模拟器回复有问题：
-
标签 0x91 在 ARPC 部分有很多个零。 然后 card 尝试验证 ARPC 和 0x91 数据，您看到拒绝： “MChip4 - 符号 81：发行人身份验证失败，拒绝交易”。 收到的 ARPC 密文与预期卡值不符。
-
发行者脚本标签 0x71 也包含带有归零数据的错误 APDU 命令。
有关详细信息，请咨询您的模拟器供应商。也许您使用的是有限的演示版本，这就是为什么您获得部分归零标签的原因。
