Is an Open-Source (preferable) or Commercial API that reads PDF417 barcodes available for IOS (iPhone / iPad)? Any observations \ lessons learned regarding the API you have implemented is appreciated. Thank you
Manatee Works is the only one I've found:
They also have an iPhone app to demonstrate the SDK:

Have a look at zxing. It is an open source project, and, according to the description, PDF 417 is supported.
