EMV：第二次生成AC结果为6985 SW_Error访问条件不满意

Question

我正在做一些EMV测试，并希望有人可以对我所看到的内容有所了解。我正在运行适用于我们解决方案的万事达M-TIP测试，并且我看到了一些意想不到的结果。当使用M-TIP 50测试卡运行M-TIP 50测试（1,2,3）时，第二个GENERATE_AC命令出现错误。我们的解决方案在技术上被定义为具有在线功能的离线，但我们目前正在完全离线的环境中进行测试。

我已经花了很多时间阅读EMV书籍并冲刷Google，但我仍然不明白为什么它会返回6985.我现在想到的最好的猜测是它有一些事情要做与CDA（这也应该在这个过程中发生？）

我已经包括第一次和第二次GEN_AC请求和响应，以显示发生了什么。如果有人能够提供有关正在发生或发生错误的信息，我将不胜感激。

Answer 1

我从我的测试工具的支持系统一些帮助。他们的反应有助于解释这样的场景：

响应1： “在你的测试用例M-TIP 50 test1的交易金额，Test2和测试3均高于最低限额，所以交易都应该但是，由于您的测试环境处于离线状态，交易无法在线处理，我可以看到第二个生成AC中的发卡行身份验证数据全部为0（它们不是由发卡行返回，而是默认值集卡片验证身份验证数据以查看数据是否由发行人返回，在您的情况下，验证失败，卡片返回“69 85”。

响应2： “的MTIP50测试用例是有点特殊。MTIP50测试用例的发行者认证数据是16字节，与正常值（10字节）不同。因此，BTT对MTIP50的发行人认证数据进行额外检查。由于发卡行认证数据是在你的情况下，所有零，模拟卡认为他们是无效“

分辨率：。 事实证明，这是与我所用的测试工具的问题，他们最近发布了一个

Answer 2

好像你做了很多“脱机批准”没有明确的计数器。

有你的情况，几个可能的原因为6985：

1）AC会话密钥计数器超限
因为在第二响应代码生成AC是“无法到网上去，请求脱机批准”卡会脱机，因此CTR会累积并且不会重置（它只会在Generate AC 2中在线重置）。

尝试个性化增加限制或完全在线。

2）的量转换期间溢出，如果交易国际 （交易货币！= CRM货币代码）。
所需的完全在线

3）添加累计金额中溢出，如果国内交易（交易货币== CRM货币代码）。
需要全Onlinе

此外，检查为什么“国家代码”是不存在的Cdol1
