SCardTransmit 返回 87 (0x57)，不知道出了什么问题。 SCardTransmit 与 SELECT 和 READ RECORD 配合使用

Question

尝试使用 ACR39U 读卡器发送 GPO 失败，错误代码为 87 (0x57)、INVALID_PARAMETERS，适用于其他读卡器。它还可以与 SELECT 和 READ RECORD 一起使用。

这是我的 APDU 日志。

00 A4 04 00 0E 31 50 41 59 2E 53 59 53 2E 44 44 46 30 31

00 B2 01 0C 32

00 A4 04 00 08 A0 00 00 03 33 01 01 01

80 A8 00 00 0A 83 08 00 00 00 00 10 00 02 12 00

对于其他读卡器，它会返回正确的响应，但对于 ACR39U，它总是返回 87。这是隔离此问题的源代码。它是用 C#、.NET8 编写的。我在 Visual Studio 中使用任何 CPU。 Windows 11。卡是银联卡。

这可能是什么原因造成的？

Answer 1

您似乎正在使用

T=0

协议（在

SCARD_PROTOCOL_T0

调用中给出

SCardConnect

）。

GET PROCESSING OPTIONS

是“情况 4”命令（详细信息请参阅 ISO 7816），需要根据

T=0

逻辑进行传输（请参阅此处）。

您的沟通应如下所示：

>> 80 A8 00 00 0A 83 08 00 00 00 00 10 00 02 12 (GET PROCESSING OPTIONS)
<< 61 XX (command successful, XX response data available)
>> 00 C0 00 00 XX (GET RESPONSE)
<< [response data] 90 00
