我正在为一个个人项目使用“摩托罗拉emdk”。我看到TagData.TagID和TagData.MemoryBankData不同（MEMORY_BANK.TID选择时）。
.NET 文档没有提供信息，它只是说明：
TagData.TagID 属性
获取标签 ID
我深入研究了“Motorola EMDK for C”API，这是 .NET SDK 封装的低级接口，它提供了更多详细信息：
UNIT8* pTagID
标签 ID，对于 C1G2，此字段是指 EPC 数据。
...这清除了一切，除了值MEMORY_BANK.EPC也不匹配TagData.TagID！
我查看了 Class 1 Gen 2 规范（http://www.gs1.org/sites/default/files/docs/uhfc1g2/uhfc1g2_2_0_0_standard_20131101.pdf），标签数据结构中描述的字段似乎都与此相对应TagID财产。
我确实想知道TagData.TagIDSDK 是否会生成一些任意的、不透明的值作为唯一标识每个标签的方法，但我注意到在不同的会话中使用相同的值，所以它绝对是确定性的，但它是什么意思？
我写了一个程序来转储标签和TagID属性的所有内存库，这就是我得到的：
TagData.TagID: "0000000000000000000C7D16" Bank: MEMORY_BANK_EPC , BankData: "743E30000000000000000000000C7D16"

更新
看来我看的不够仔细！
TagData.TagID包含在 中，EPC例如：
TagData.TagID: "3330323135385F303031" Bank: MEMORY_BANK_EPC , BankData: "EB1728003330323135385F303031"
EPC: "EB1728003330323135385F303031"
TagID: "3330323135385F303031"
根据 C1G2 规范，EPC 的开头保留如下：
0x0000 to 0x000F - StoredCRC - 0xEB17
0x0010 to 0x001F - StoredPC - 0x2800
0x0020 to 0x020F - Actual EPC value - 0x3330323135385F303031
0x0210 to 0x021F - XPC_W1 (Optional) - null
0x0220 to 0x022F - XPC_W2 (Optional) - null
那就清楚了！
但我现在的问题是：可以TagID相信它是全球独一无二TID的吗？我的理解是EPC不需要唯一，它只是一个任意字符串而不是序列号。如果是这种情况，那么在 EPC 冲突的情况下会发生什么？
