qr-code

i can't figure out how to build a OR Code for a Pass that is scannable with the new QR code scanner in iOS7' Passbook App. When I try to scan a QR Code with a link to a working Pass, the App says it is 'No Pass available for this Card'. Card, hum?! Any ideas? For a pass to install, the following criteria have to be met: The link must be https The URL must return a valid .pkpass bundle The Content-Type header must be application/vnd.apple.pkpass Unfortunately, these requirements are not yet documented, but they are mentioned in the WWDC session What's new in Passbook The URL contained in the QR

I'm trying to make a QR Code Generator for OS X but i haven't had succession in making a QRCode that can be more colourful that the black and white ones I'm using the CIQRCodeGenerator for the CIImage Filters how would i make this work I've got a sample code that I've implemented into my app :- + (NSImage *)createQRImageForString:(NSString *)string size:(CGSize)size { // Setup the QR filter with our string CIFilter *filter = [CIFilter filterWithName:@"CIQRCodeGenerator"]; [filter setDefaults]; NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding]; [filter setValue:data forKey:@

I'm trying to insert and read qrcode's from PDF files. To create/read qr codes from images i'm using zxing project and to manipulate the pdf i'm using Big Faceless PDF . Everything works well if i create the QR Code, insert into my pdf, and then read the images from the pdf and convert the correct one to QR Code. However , if i try to to read images from a scanned document (with a qr code sticker attach to it), i cannot obtain the qr code image from the pdf (the only image i can get, using Big Faceless PDF, is the document it self). Does anyone knows a Java library to search in pdf files for

Client wants a button on the mobile web app that launches a QR code scan (with camera on iPad) then returns to the mobile web app with the QR code info. Wondering how best to achieve this and/or if it's even possible. Thanks! Sean Owen Yes, see the zxing: URL format here . Not really possible, sorry. The closest you can get is some apps have a URL scheme ( redlaser:// , for example) that you could provide a link to. There's no way of detecting that they've got the app installed, though. The best thing would be to use a bluetooth barcode scanner. Something like Socket scan , CX2864-1336 would

I followed this tutorial on how to build an Android app that can scan QR codes. Here's the full code. I added the Google Play services using grade like so compile 'com.google.android.gms:play-services:7.8.0' . AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="bitinvent.io.qrscanner" > <meta-data android:name="com.google.android.gms.vision.DEPENDENCIES" android:value="barcode"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.CAMERA"/>

I am writing a qr code decoder using Zbar api. I am using windows pre built libraries . I used the following code to load the image to ZBar IplImage *src=cvLoadImage("image.png",CV_LOAD_IMAGE_GRAYSCALE); ImageScanner scanner; scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1); int width = src->width; int height = src->height; uchar* raw = (uchar *)(src->imageData); Image image(width, height, "Y800", raw, width * height); int n = scanner.scan(image); But it failed to decode the image. Am I using the correct way to read image data using opencv ? . When I tested only one image decoded and failed

I am making a barcode reader app which is free. I am looking for free SDK to decode Datamatrix,QR,Aztec,UPC,EAN barcodes. I have implemented ZBar SDK as per now. Which detects QR,UPC and EAN successfully. I tested This link Zbar ZXingOBjC But none of these are able to detect Aztec properly. With Data Matrix,UPC,EAN and QR i found Redlaser very effective but now its not free. Now, is there any free SDK available to detect all four barcodes without paying as i want to keep my app free on app store. Please suggest P.S I want compatibility of scanner with latest iOS available. You scan customize
