EMV：在6985中第二次生成AC结果SW_Error不满足访问条件
我正在进行一些EMV测试，并希望有人可以了解我所看到的内容。我正在运行适用于我们解决方案的Mastercard M-TIP测试，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，我在第二个GENERATE_AC命令上遇到错误。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脱机的环境中进行测试。
我花了很多时间阅读EMV书籍并搜索谷歌，但我仍然不明白为什么它会返回6985.我现在能想到的最好的猜测是它与它有关CDA（这也应该在这个过程中发生？）
我已经包含了第一个和第二个GEN_AC请求和响应，以显示正在发生的事情。如果有人能够深入了解正在发生的事情或出现的问题，我将非常感激。

2 个答案:
答案 0 :(得分：4)
好像你做了很多“离线审批”而没有明确的柜台。
对于6985，您可能有几种可能的原因：
1）超出AC会话密钥计数器限制
由于第二代AC中的响应代码为“无法联机，请求离线审批”卡处于脱机状态，因此CTR会累积并且不会重置（仅在重置时生成AC 2中的“重置”）。
尝试个性化增加限制或完全在线。
2）转换金额时溢出，如果是国际交易
（交易货币！= CRM货币代码）。
需要完整在线
3）在累计金额期间溢出，如果交易国内（交易货币== CRM货币代码）。
需要完整的Onlinе
另外，检查为什么“国家代码”在Cdol1中不存在
答案 1 :(得分：2)
我从测试工具的支持系统那里得到了一些帮助。他们的回答有助于解释这种情况：
回复1： ＆＃34;您的测试用例M-TIP 50 test1，test2和test 3中的交易金额都高于最低限额，因此交易应该上线。但是，由于您的测试环境处于脱机状态，因此无法在线处理事务。我可以看到第二个生成AC中的颁发者认证数据都是0（它们不是由发行者返回的，而是由终端设置的默认值）。该卡验证认证数据以查看发行者是否返回数据。在您的情况下，验证失败，卡返回＆＃34; 69 85＆＃34;。＆＃34;
回应2： ＆＃34; MTIP50测试用例有点特别。 MTIP50测试用例的发行者认证数据是16字节，不同于正常值（10字节）。因此，BTT对MTIP50的发行方认证数据进行额外检查。由于发行人身份验证数据在您的情况下都是零，因此模拟卡认为它们无效。＆＃34;
解决： 事实证明这是我使用的测试工具的一个问题。他们最近发布了他们软件的新版本，这种情况不再发生。
