We are not looking for perfect solution - since the PDF417 is pretty complex and needs a very good camera with auto-focus, we can accept that it will be working only on few pre-selected high end devices.

We were looking also for commercial SDK, also here on stackoverflow, but with no luck.

It really depends on what you expect. Simple PDF417 reads pretty instantly, like... this or this.

这将永远不会被扫描。

界线的东西，是小型或中等复杂程度：例如1 和例如2

Borderline is stuff that is small or moderately complex: example 1 and example 2.

我可以读取第一而不是第二，即使第一是致密 - 大小有助于

I can read the first but not the second, even though the first is denser -- size helps.
