I have two phones, one has a 3.2MP camera, and the other has an 8MP camera. I downloaded the 'Barcode Scanner ' app on both phones, it works on the 8MP phone but the 3.2MP phone sometimes doesn't pick up any barcodes at all.
Update: from the discussion in the comment thread, it seems the phone doesn't pick up barcodes because it doesn't have Auto Focus. Is there a way I can get around this?

How can I scan participants' QR tickets to enter an event?

I am hosting an event where I would like to have all participants receive a secret key in the form of a SHA-hashed secret, converted to a QR code. This would represent their ticket to enter the event. I would then like to be able to use a large list of these secrets to verify the participant's ticket (QR code) and automatically mark that participant as present, to make sure no tickets are used multiple times.
Is there a way to use QR codes to verify if a certain value is in my list of keys, and then check off that particular key? Or is there another way I could use such a QR-based ticket system to verify a participant's ticket? Would I somehow need to write my own app to do that, or are there already existing systems I could use for this?
If I am posting this in the wrong place, please let me know where I should post it instead. I couldn't think of any better place than here.

We are trying to print Barcode using USB Barcode Printer from an android device.
The available printer model is GODEX EZ520, we used printer-share app from Playstore and it detected the printer-device but they do not have supporting drivers for this printer.
Do we need to write separate drivers for printers to print from android or Is there any other ways to connect android device and Barcode Printers via usb.

I have a intranet webpage that has a button that launches a barcode scanner app, basically by calling the app through a link to the company's webiste:
Scan Sales Order
When one clicks on this link a modal pops up with 'Open with Barcode Scanner' and the Just Once or Always buttons.
If I click 'Always' it never remembers. Anytime we click the button to scan, it always asks. How do I override this, or just force it to use the default app without prompting me?

I would like to set up a bar code reading app (such as ZXing Team's Barcode Scanner) on an android phone in such way that it would send with as little user interaction as possible (preferably none) after the barcode was scanned the result in an SMS to a predefined phone number.
I have tried Tasker but without success and I don't have the skills to write an app of my own.

Use Android device as a barcode reader for PC
Is there an app that allows your Android device to act as a barcode reader, in such a way that it can send something like keyboard inputs to a computer in real-time?

I have a 10 Galaxy Tab S (Android 5.0.2) on which I am connecting a barcode scanner via USB OTG.
The problem is it does not read the barcodes (Line,2-D, QR ) accurately. It missed out on some characters.
I have tried the same scanner with the same codes on a computer, a MI Phone & a Samsung Note -II Phone & it works there correctly.
Any Ideas ?

Using Firefox for Android, I occasionally find web pages containing barcode images (or photos containing barcodes) that I would like to scan.
I could save the image, switch to a barcode app, open and scan the image there, and probably end up relaunching the browser to see the result, but I'd *prefer* to long hold the image and launch the scanning app directly (with no save step required).
Is there an open source extension (Android app, Firefox add-on, Firefox app) that can achieve this? I've tried looking on the Firefox add-ons and apps marketplaces with no luck.
Example images:
* f-droid.org (rendered image, imperfect QR code)
* cryptojunky.com (photo, imperfect QR code)
* wikimedia.org (rendered Aztec code)

I have a third party app for a production system. This is now a legacy application that may not be modified.
There is a text field in this third party app.
I have barcodes that translates into valid inputs for this text field.
I would like to be running this third party app, but somehow be able to use an android device to zap a barcode, translate it into text, and stick it into that text field.
I imagine the following:
- User opens third party app
- User places focus on text field
- User presses button to cause barcode to be scanned
- Barcode is translated and placed in the text field that has the focus
Is this feasible with an android phone or tablet?
I am scared that we may have to ditch our legacy app and develop fresh.

Once in a while I see a description of a program that is to be installed via Android market. It is often accompanied by a two-dimensional barcode looking like a QR code that I guess somehow contains a link to the right Market page and the process of using it should be very easy.
I've searched and the closest thing I found is this question about reading QR Codes which makes me think it shouldn't be that hard and so I can't see whether that question is about the same usecase I'm asking about.
How exactly to make use of such barcodes? What's the way to proceed from the QR code on a web page to Market page?
