智能卡写入错误

Question

我正在开发智能卡。我在智能卡中创建了MF（主文件），DF（专用文件），EF（基本文件）。 EF文件用于存储数据。此EF可能是透明文件或面向记录的文件。我已经使用00D1000008 540100 5303 010203这个命令将数据写入透明文件。我也尝试使用00DD000008 540100 5303 010203这个命令来写入面向记录的文件。但我得到错误（6700错误代码）错误的长度。我需要解决方案来编写面向智能卡EF记录的文件。请指导我。

我已经使用winscard.dll

读命令工作正常。看到屏幕截图

看来你使用P2的一个未定义的编码与奇指令UPDATE RECORD命令。另外，您必须在P1中指定记录编号。对于这三个最显著位使用

• 100更换
• 101-逻辑与
• 110-逻辑或
• 111-逻辑异

如果你的目标写/更新完整的小长度记录，你可以考虑在even指令下使用这些命令。然后，您可以删除偏移量DO（0x54），并仅传输完整记录（任意数据DO（0x53）的值）。
