When you’re able to connect your on and offline marketing efforts, you can tell a stronger brand story, give your audience the opportunity to learn more about your product or service, and track your marketing efforts as a collective unit, rather than in silos. Adding to this the difficulty associated with tracking their effectiveness, the results of these investments can often disappear into the abyss. However, given that it often calls for third-party printers and suppliers, these campaigns can be costly and require a big time commitment. Offline marketing presents valuable opportunities for you to gain brand visibility in ways online marketing can’t. The gap that now needs to be bridged is the ability to track the effectiveness of our offline marketing efforts, online. These turning points in technology were integral to the effective use of QR codes, which isn’t all that surprising, considering that in 2018, not only did 2.3 million people own a smartphone, but they spent roughly 3 hours on it each day.Īs we all know, this sweeping increase in mobile phone and internet usage has changed the face of modern marketing, placing more emphasis on digital strategy and communications than ever. Why QR codes are the link between your on and offline marketing effortsĪlthough these codes have been around for 30 years, their sudden skyrocket in popularity over the past number of years is due to two major innovations, the mobile phone, and the internet. Think of QR codes as a signature you can add to both physical and digital assets, which directs readers to a landing page or website of your choice.

As inferred by their name, the information stored within is quickly read by smartphones, making them a valuable addition to anyone’s marketing toolkit. QR, short for Quick Response codes are square, black and white barcodes used to store machine-readable information.

Let’s take a look at how to use QR codes in your marketing strategy. QR codes hold more information than a traditional barcode and act as a scannable link that connects the physical and online world. Everything will become clear in a while.Although QR codes have been around since the 90s, the last decade has seen them shift to become more widely considered marketing assets. Don’t worry if something sounds weird or if you don’t totally understand right now. This class in combination with theAVCaptureMetadataOutputObjectsDelegate protocol is used to intercept any metadata found in the input device (that is the QR code captured by the device’s camera) and translate it to a human readable format. The AVCaptureMetaDataOutput class is the core part of QR code reading. In this case, the output of the session is set to an AVCaptureMetaDataOutput object. The AVCaptureSession object is used to coordinate the flow of data from the video input device to outputs. To perform a real-time capture, we instantiate an AVCaptureSession object and add the input of the video capture device. As we are going to capture video data, we call the defaultDeviceWithMediaType method with AVMediaTypeVideo to get the video capture device. You use a capture device to configure the properties of the underlying hardware. addInput ( input as AVCaptureInput )Īn AVCaptureDevice object represents a physical capture device.

The app works pretty much like a video capturing app but without recording feature. Keep this point in mind as it’ll help you understand the entire chapter. That’s why the barcode scanning feature is added in the AVFoundation framework. Before I proceed to discuss the demo app, it’s important to understand that any barcode scanning in iOS including QR code is totally based on video capturing. The demo app that we’re going to build is fairly simple and straightforward. After going through the tutorial, you will understand how to use the AVFoundation framework to discover and read QR code in real-time. In this tutorial, we will build a similar QR code reader app but in Swift. Some time earlier, Gabriel wrote a great tutorial on QR code. As an iOS developer, you may wonder how to empower your app to read QR code. It appears in magazines, newspapers, advertisement, billboards and even name cards. In recent years, the use of QR code has been on the rise.
