推荐答案

状态字69 82(不满足安全状态")通常意味着您当前的身份验证状态不足以访问卡上的某些资源.例如.如果响应UPDATE BINARY命令而得到该消息，则您可能无权更改文件的内容.同样，如果您是通过响应READ BINARY命令得到的，则可能没有权限从文件读取二进制数据(随机访问).

The status word 69 82 ("Security status not satisfied") typically means that your current authentication state is insufficient to access a certain resource on the card. E.g. if you get that in response to an UPDATE BINARY command, you might not have permission to change the content of the file. Similarly, if you get that in response to a READ BINARY command, you might not have permission to read binary data (random access) from the file.
