当我用android应用程序扫描内华达州驾驶执照背面条形码pdf417时，我得到不可读的数据。

数据是什么?如何读取，修改和创建新的相同的pdf417条形码?
他们是对的，你只是得到一个例子。如果你扫描你的真实身份证，它会显示你的个人信息。
示例如下:

你可以用这个检查你的。https://online-barcode-reader.inliteresearch.com/
这是AAMVA手册的链接，去附件D第46页，它会在那里解释一切。

祝你好运!
是DL数据的字符串。你一定是在看样本，因为里面没有数据。
ie - DCSLASTNAME = DCS是标题"对于姓氏-那么下一个XXX字符应该是许可证上的姓氏。
研究将带您到这里:https://www.aamva.org/FL-ITN-DriverRelatedCredentialPrintSolutionExh3-022016/了解标准以及如何从DL条形码中解析数据。
