I'm developing an iphone and android app that uses very simple barcode scanning. We've narrowed our barcode type to 2D, particular either QR or DataMatrix.
I've written two quick and dirty apps using Scandit and Zxing (using mostly their sample code) to test and compare, and I've found Scandit to be so much faster in acquisition and decoding, but more importantly, far more accurate.
Disclaimer: For my tests, I was using online barcode generators and printing them on my laser printer -- not sure if that matters.
Question: Does this sound typical? I'd like to use Zxing given it's opensource support, but I'm concerned about it's reliability. Any insight into this, particularly the trustworthness of Zxing for QR and/or DataMatrix would be very appreciated!
I would try scanning with Barcode Scanner to rule our your code. It represents how ZXing ought to work on an Android device.
If you can't scan QR codes very easily then something is wrong with the device. Try the device bug workaround settings.
DM is not as strong as QR codes. You should find it works though. again just try the app.
On a desktop this changes and you need to enable hints like TRY_HARDER. but not on mobile.

I am looking for some advice on scanning barcodes into our web app via post/get etc.
We would be looking to use some kind of handheld scanner with a mobile computer built in (windows or linux etc.) and wifi.
I have done some reading and found a few articles on using an iPhone but cant find anything explicitly using a standalone scanner, so would like to get some advice before we buy one and give it a go.
Has anyone done this before?
While not strictly a programming question, yes, we did that. We use a Honeywell Dolphin 75e device with Android, it has a superb scanning engine, to just do this: Scan data and transmit it via HTTPS.
I am looking for an HTML/javascript sample that I can use on a windows 8 app to read barcodes.
There are a couple apps that can read barcodes in the store. However, they must be using something like C# because I was not able to find a sample that uses HTML/Javascript to be able to read barcodes. I know barcodes have specific requirements, but I am just looking for a sample here.
Does anyone know where I can find a simple sample?
Thank You for reading.
Yes - ZXing is an open source library for reading 1D and 2D barcodes. There are a few ports including one for WinRT which can be found here: http://zxingnet.codeplex.com/. You should be able to reference this in your application as a component and call it from WinJS.
Hi you can check this link:
http://www.activebarcode.com/ - Provides a barcode API for your APP. It can also be used with VB.net, C#. It also provides you a different kinds of barcode formats.
Hi,
I made a lib for WinRT using ZXing & Imaging SDK.
It works well (but does not include any additional focus feature).
https://github.com/stepheUp/VideoScanZXing4WP81
There is a lib and a sample app that you can try.
It works for barcodes and QRCode (barcode by default but just change the optional parameter in the scan function code to use QRCode)
Hope it helps,
Stéphanie
I'm developing an android application where in I generate data matrices and allow users to input them using zxing for scanning them.
However, there was a license issue raised asking if all the formats scanned by zxing available open source.
It's not about the application zxing but the formats it scans. Are all those formats usable under some or other open source license. If not, which scannable formats are open source usable ?
Yes, all are open, or else they wouldn't be implemented. For example, MS Tag is not there. Data Matrix was originally patented and proprietary when invented, but at this point is ISO standard 16022 and is public domain. Something similar happened with QR Codes, for example.
Im using the ZBarSDK barcode reader in my app, but it is not compiled to run on arm7s.
Im wondering if I should rather use a different library for my barcode scanning.
Im experiencing some problems with ZBarSDK, like problems with reading barcodes on some devices.
I ended up paying for the SD toolkit barcode scanner, since I did not like the ZBar license agreement.
Just remove the "armv7s" on ZBarSDK, this will work :)
You can use the beta version (1.3.1), which is working fine with optimized arm7 arch.
I want to scan products barcode using zxing libray in my Windows phone application .
I'm worndering how to integrate it into the project and how to use it .
thank's in advance .
There is a silverlight port of zxing here that works on WP7: zxing
Just a little addition for everybody that also searches about this topic: Stéphanie Hertrich built a small sample application that uses the zxing library together with the new Mango Camera API. This way you can search the live camera stream for barcodes and stop immediatelly if something was found. This is much more convenient for the user (just tried it for myself).
Her code is not fully tested, but it works well for a demo and finds those barcodes unbelievably fast (its really impressive, it mostly found it just after the autofocus finished).
