Generate 2D bar code (e.g. QR Code, Data Matrix, PDF417) on iPhone and Android

Question

I need a library to generate a 2D bar code on iPhone and Android (and preferably WM7 and possibly j2me too) - the idea is to transfer information to another device with a corresponding scanner (decoder). What are the good options?

ZXing is an option, in particular for the reading/decoding aspect, but I want to generate them on these devices.

Answer 1

Best option should be ZXing's library. I'm not sure about the Windows Phone 7 support tho.

Answer 2

I tried all solutions described above with no success, but then found this library: akopanev-iOS-QR-Code-Encoder

Open-source, simple to implement, has sample xcode project, works great
