I need a bar code engine to support above 3 bar code types (1D, QR code, data matrix) for iPhone. I tried zxing, zbar which in my case doesnt support data matrix. I found some commercial versions also.

But I am looking for a free SDK.

  • Thanks Till and Brad. Yes there are many and what I want to find is a bar code reader which supports 1D, QR code, data matrix and also it should be free. Currently I could not find any :( – Dilshan Apr 17 '11 at 16:39
  • one type I am not finding is pdf417. – harshalb Jan 31 '12 at 07:42
  • AFAIK, zxing supports QR, data matrix and 1D. You just need to include the decoders you want the images to go through. – Nick Aug 09 '12 at 20:31
  • @harshalb we also didn't find proper PDF417 scanner SDK, so we developed our own. More info on http://pdf417.mobi – ssasa Sep 19 '13 at 20:47
  • @ssasa This is a very old thread. Now you can find many alternatives for this. – Dilshan Sep 20 '13 at 04:59

This question is very old, but I'd like to answer it anyway for completeness. I would recommend zxing, as it supports all the codes mentioned in the question.

However, since iOS7 there is also the option of using the built-in scanner API (which I have found quicker and more accurate than zxing after a couple of hours testing). I also found the Cocoa APIs slightly easier to integrate with a custom UI. The downside is that (to my knowledge) Data Matrix is not supported.

A third option would be to use a clever combination of both, maybe also to fall back gracefully for pre-iOS7 devices.

  • Well, fair enough. I actually used Xamarin when testing this anyway :) – Krumelur Dec 03 '13 at 13:04
  • Thanks for replying. Yes zxing had that support now. Back in the day there was no proper barcode reader to read all type of barcodes. I believe now they have improved a lot and they support most of the barcodes. – Dilshan Dec 04 '13 at 16:41

As of iOS 8, Data Matrix is supported in AVFoundation. see:
