Code to turn on mobile camera for QR codes

  • Hi there,

    I’m not sure if this is the right place to post this, but I’m looking for a feature or plugin which might help me out. Im currently developing a mobile website for my company that allows users to scan QR-codes on our tradeshow which will take them to the company page for the specific company they’re visiting on our tradeshow. What I’m looking for is to make a menu item called “Scan”. When people click on “Scan”, it should open the rear camera on their mobile phone, so they can scan the QR-codes.

    Is there a way to achieve this? I’ve tried searching for plugins that allow this but I couldn’t find one. I know my way around plugins, HTML and CSS, but I am in no way an expert developer so I was hoping if the solution would be doable for me.

  • Not sure if this tutorial from Google fundamentals is too much for you, but if you want to build yourself it is a good starter https://developers.google.com/web/fundamentals/media/capturing-images

    I had a play around with a few things, and I don’t think it will help.

    I can open the camera stream and display it on the page. I can open the native mobile camera, but that doesn’t (on my phone ) enable the QR reader.

    I’m not really sure about the usecase here – as you want to put a button on your website and then from that button read a QR code to go to a website? As they already have to be on a website – why not just provide links?

    Hi Alan,

    First of all, thanks so much for your response and willingness to help.

    The usecase here is that people will walk around a tradeshow and visit different exhibition stands. People will have to scan the first QR-code in order to go to a registration page. We will provide QR-codes on each and every stand so people can quickly visit the company page of the respective stand they are standing before. But we’ll need a way for them to be able to scan the QR-codes, hence the ‘Scan’ button in the menu. Or is this not user friendly? We thought that it would be if people would quickly be able to scan the QR-code and go directly to the company page.
