APDU使用ACR122U读卡器在mifare 1K上写入块命令

Question

请，

我正在尝试使用ACR122U阅读器编写一个简单的二进制块来识别1k标签。

我正在尝试写入块，5个字节，文本：＆＃39; teste＆＃39;读回来。

但是在更新此块时我总是收到错误6300。

有什么想法？

我正在使用Windows 8.1 / delphi xe8。

我的日志是：

可以轻松解决此问题

您正在写一个块，您必须提供完整的信息块。 Lc的唯一选项是x04或x10 - 四个字节或十六个字节。对于Mifare 1K，它很清楚你需要提供16个字节。您只有5个字节的数据，因此用零填充其余部分。

|  CMD   | block1 | 16 bytes | data ... 
 FF D6 00    01       10       74 65 73 74 65 00 00 00 00 00 00 00 00 00 00 00
