How To Use

Launch

The Journal window displays previous QR captures and provides a toolbar necessary for scanning new codes.

Scan QR Code

Clicking the scan button will open the scanning sheet. The app will use your camera to start scanning for QR codes. Simply hold up the code so it is fully displayed in the camera. Once read, the text or URL of the QR code will be displayed.

You can then:

• Save the QR code to your journal.
• Skip this QR code and keep scanning.
• Cancel scanning.

Import QR Code

If you don't have a Mac with a camera or have an image of a QR code, choose the import option. An image import window will appear for you to drag the image into. If successfully scanned, the text or URL from the QR code will be displayed.

You can then:

• Save the QR code to your journal.
• Skip this QR code and keep scanning.
• Cancel scanning.

URL Watch - AppleScript Support

The URL Watch feature allows for an AppleScript to be run after a successful scan. QR Journal will look for a function in the script named scanned_code and will pass the scanned QR code text as a parameter. Here is a sample that displays the scanned URL is a dialog:

QR Journal is an advanced program that allows you to scan and store any QR code (2D barcode) by displaying the code in front of your webcam or selecting a photo with a QR code from your local folders. This efficient tool comes with a freeware license; therefore, you will never have to worry about registering/acquiring the program.

In 2015 I had written an HTML5 based QR code scanning library as a jQuery extension. Recently I realized there was some consistent traffic on my Github Project and the demo page. As I dug more into what was going on and I was embarrassed to see the poor design and obsolete support to the latest HTML APIs around Camera. I recently fixed some of the issues and refactored the javascript library that is now independent of jQuery library and supports

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

• Removed jQuery dependency
• Refactored the APIs to return Promise rather than being purely based on callbacks.

Introduction

QR Code is a very common technique of encoding information as images. Its a very common used in physical stores for identifying products like bar code is used.

The javascript library available at mebjas/html5-qrcode on Github allows users to add a QR code scanner in their web applications. It works cross-platform and across different devices like PC, Mac or smartphones. It uses the

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

Demo

A demo for this project is hosted at https://blog.minhazav.dev/research/html5-qrcode.html

How to use

Download the Javascript code or use the Github version

The code is hosted at mebjas/html5-qrcode on Github. You can download the library and add it to your codebase from release page or use it directly like:

<script src="https://raw.githubusercontent.com/mebjas/html5-qrcode/master/minified/html5-qrcode.min.js"></script>

I highly recommend using the minified version for the following reasons:

• It’s smaller in size and would load faster.
• The actual code

  <script src="./jsqrcode-combined.js"></script>
  <script src="./html5-qrcode.js"></script>
  

  7 is written using ECMAScript which is supported only in the latest browsers. It may not be supported in older browsers. The minified script has been transpiled using

  <script src="./jsqrcode-combined.js"></script>
  <script src="./html5-qrcode.js"></script>
  

  8.

Not recommended If you still wish to use the non-minified library, try including these:

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

Add a palceholder element in HTML

<div id="reader"></div>

Add an empty HTML element at the appropriate position in your HTML code, give it an

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

Enumerate all available cameras

The

<div id="reader"></div>

<div id="reader"></div>

// This method will trigger user permissions
Html5Qrcode.getCameras().then(devices => {
  /**
   * devices would be an array of objects of type:
   * { id: "id", label: "label" }
   */
  if (devices && devices.length) {
    var cameraId = devices[0].id;
    // .. use this to start scanning.
  }
}).catch(err => {
  // handle err
});

The returned object is an

<div id="reader"></div>

<div id="reader"></div>

• <script src="./jsqrcode-combined.js"></script>
  <script src="./html5-qrcode.js"></script>
  

  9: Id of the camera. This is needed to start scanning the QR Code.

• <div id="reader"></div>
  

  5: Label for the camera. This is human-readable name for the camera device like

  <div id="reader"></div>
  

  6 or

  <div id="reader"></div>
  

  7.

Once you have cameraId you can perform start/stop operations

Starting the camera implicitly starts QR Code scanning. It runs at a certain fps (frame per seconds) provided in configuration argument. This is an optional field and by default the scanner runs at 2 fps.

To

// This method will trigger user permissions
Html5Qrcode.getCameras().then(devices => {
  /**
   * devices would be an array of objects of type:
   * { id: "id", label: "label" }
   */
  if (devices && devices.length) {
    var cameraId = devices[0].id;
    // .. use this to start scanning.
  }
}).catch(err => {
  // handle err
});

<div id="reader"></div>

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

// This method will trigger user permissions
Html5Qrcode.getCameras().then(devices => {
  /**
   * devices would be an array of objects of type:
   * { id: "id", label: "label" }
   */
  if (devices && devices.length) {
    var cameraId = devices[0].id;
    // .. use this to start scanning.
  }
}).catch(err => {
  // handle err
});

// This method will trigger user permissions
Html5Qrcode.getCameras().then(devices => {
  /**
   * devices would be an array of objects of type:
   * { id: "id", label: "label" }
   */
  if (devices && devices.length) {
    var cameraId = devices[0].id;
    // .. use this to start scanning.
  }
}).catch(err => {
  // handle err
});

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);
});

Extra optional configuration in start() method

The configuration argument in start() method can effect both scanning behavior and UI. There are two optional properties right now, if you don’t want them you can just pass an empty

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);
});

fps - Integer, Example =

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

0

Also known as frame per seconds, the default value for this is

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);
});

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);

Use this property to limit the region of the viewfinder you want to use for scanning. The rest of the viewfinder would be shaded and ignored by the QR code scanner. For example by passing config

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);
});

This is an optional property, if nothing is passed, the scanner will scan the entire region of the viewfinder.

To stop scanning, use stop() method

The

// Create instance of the object. The only argument is the "id" of HTML element created above.
const html5QrCode = new Html5Qrcode("reader");

html5QrCode.start(
  cameraId,     // retreived in the previous step.
  {
    fps: 10,    // sets the framerate to 10 frame per second
    qrbox: 250  // sets only 250 X 250 region of viewfinder to
                // scannable, rest shaded.
  },
  qrCodeMessage => {
    // do something when code is read. For example:
    console.log(`QR Code detected: ${qrCodeMessage}`);
  },
  errorMessage => {
    // parse error, ideally ignore it. For example:
    console.log(`QR Code no longer in front of camera.`);
  })
.catch(err => {
  // Start failed, handle it. For example,
  console.log(`Unable to start scanning, error: ${err}`);
});

<div id="reader"></div>

<script src="./jsqrcode-combined.js"></script>
<script src="./html5-qrcode.js"></script>

html5QrCode.stop().then(ignore => {
  // QR Code scanning is stopped.
  console.log("QR Code scanning stopped.");
}).catch(err => {
  // Stop failed, handle it.
  console.log("Unable to stop scanning.");
});

This should only be called after QR Code has been started successfully.

For more clarity I have dumped the

html5QrCode.stop().then(ignore => {
  // QR Code scanning is stopped.
  console.log("QR Code scanning stopped.");
}).catch(err => {
  // Stop failed, handle it.
  console.log("Unable to stop scanning.");
});

This code uses jQuery but it’s not really needed.

IOS

Apparently, Webkit for IOS is used by Chrome, Firefox, and other browsers in IOS and they do not have webcam permissions yet. There is an ongoing issue on fixing the support for iOS - issue/14

Existing issues and plan to fix them

In milestore/v1.0.1 I plan to fix compatibility issues with

html5QrCode.stop().then(ignore => {
  // QR Code scanning is stopped.
  console.log("QR Code scanning stopped.");
}).catch(err => {
  // Stop failed, handle it.
  console.log("Unable to stop scanning.");
});

html5QrCode.stop().then(ignore => {
  // QR Code scanning is stopped.
  console.log("QR Code scanning stopped.");
}).catch(err => {
  // Stop failed, handle it.
  console.log("Unable to stop scanning.");
});

Does Apple have a free QR reader?

How do I connect a QR code to my Mac?

Can you just scan a QR code without an app?
