Mifare Desfire / Mifare plus无法使用ACS ACR1252进行读取

Question

嗨，我是RFID阅读的新手。因此，我首先从github下载了pcsc sharp存储库。然后我尝试从普通的rfid标签中读取二进制数据，它工作得很完美，但下一步是从我认为是模拟的rfid标签中读取数据。射频识别标签控制器采用pn71501。在使用pcsc sharp的这个标记中，我无法读取除ATR和uid以外的任何数据。我试着用我的iPhone读取这个标签，它读取了它。那么我做错了什么呢？

我也尝试使用已经完成的软件，但它也不能读取它。

以下是我使用NFC工具得到的结果：

我使用的PS智能卡读卡器是ACS ACR1252

下面是我的代码：

Answer 1

我知道呀。我之前查过了。你能用文件资源管理器读卡吗？

像UART这样的硬件设备可以在三个不同的级别上读取

通过驱动程序查找硬件I/O address

• Read/Write，

1. 直接读写UART。在c#中使用开放式串行端口。驱动程序通过应用程序获取硬件I/O
2. 读/写。应用程序执行上面的%1和/或%2。

您有一个正常工作的应用程序(编号为3)，我不知道它使用的是方法1还是方法2。

使用读卡器，我会尽量让你的编程变得简单。如果你有一个API，最简单的方法是3。下一个最简单的方法是方法2，如果您安装了供应商驱动程序，则应该能够使用该方法。您应该会在设备管理器中看到设备。

要解锁卡(加密)，您还需要安装证书，而不是卡附带的证书。文件资源管理器应该能够读/写卡。
