title: Generate 2D bar code (e.g. QR Code, Data Matrix, PDF417) on iPhone and Android
body: <p>I need a library to <em>generate</em> 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?</p>
  
  <p><a href="http://code.google.com/p/zxing/" rel="nofollow">ZXing</a> is an option, in particular for the reading/decoding aspect, but I want to <em>generate</em> them on these devices.</p>
