![]() There is also the option to create a small application that will only take on the function of reading codes. You can, of course, make a full-fledged mobile version of the main web application, but this is a long, expensive task and requires further support. ![]() The user has to exit the main application, switch to the application for recognition, and generally use a mobile device. In this case, recognition is reliable, but the system is incohesive. How does it work? You can create a barcode reader application in React Native that will pass information to the main system. But this kind of barcode scanning software is usually quite expensive.Ĭons: high costs, strict payment schedule Standalone application ![]() Fees vary by plan and provider for example, you can pay by the number of scans or by time. The main issue is paying for this service on time. An external API, similar to payment gateways, is simply added to the application. How do they work? They allow you to scan a QR code with a browser by delegating recognition to a third-party service that processes your images on their servers for a fee. Also, a huge disadvantage of this type of free barcode reader software is its gigantic size, which affects the performance of the entire application.Ĭons: extremely low percentage of correct recognitions Paid services For example, one of the popular JS QR code decoder libraries in our tests gave only one correct recognition out of five. They try to recognize bitmap images from the camera right in the browser, but they are very unreliable at this task. How do they work? Usually, these free JavaScript QR code scanner libraries are easily integrated into web applications, but they typically do not work well. JavaScript libraries for image recognition There are also paid services and huge libraries, and we will talk about them and other SDKs for decoding barcodes below. Later, smartphones came to the rescue, but they required a separate application that needed to be synchronized with the main system. More often, businesses chose separate devices for this purpose, which worked well, but was quite expensive. Teaching a web application to read barcodes was a very difficult task a couple of years ago, since it is impossible to access computing power through a browser. However, most corporate software and CRMs are web applications, so B2B requires browser-based barcode reader software solutions. Most modern smartphones have separate cores for processing graphics and video, and then the main application can use their power to recognize codes. If the main product is a mobile application, there is no recognition problem. As a result, we checked all the available solutions that offer the ability to read barcodes online from a web application, and we will talk about their pros and cons below. On one of our projects in 2020, we were faced with the need to add barcode scanning to the Loreal Academy web application for product accounting. ![]() Therefore, our customers require barcode scanner software solutions. We buy goods, pay bills, and even make purchases with them. All screenshots by Sayak Boral.Barcodes and QR codes are almost everywhere. Additionally, there are numerous online QR generators available. Since Google Chrome has a built-in QR code generator, using it is the simplest option: right-click any page or image and choose Create QR Code. To test any of these methods of scanning QR codes on Windows, you should know how to create your own QR code. The URL itself will need to be corrected. Missing or broken links: if the URL connected to the QR code is not working properly, it may lead to a 404 error.You also need sufficient nits of screen brightness on your laptop screen. QR code is blurry/not clear: move to well-lit surroundings.It would be better to take a photo of the QR code and upload the file manually on a laptop. Likewise, if it’s too tiny, you may not be able to capture it on your laptop camera, as it doesn’t have a Zoom feature. QR code is too big or small: if the QR code is displayed on a cutout or billboard, you may not be able to picture the entire image on a laptop screen.Read through these tips for each of these scenarios: It is heavier to move around, and the camera resolution often tops out at 720p, which leads to several kinds of QR code scanner problems. Troubleshooting Tips for QR Code Scanning on a LaptopĪs we may know by experience, a laptop isn’t ideally suited for scanning QR codes. Learn how to prevent background apps from causing interruptions. Tip: a slower Windows device can cause delays in activities like QR code scanning. No matter which option you use, once the QR code is scanned, the results will appear in the QR code text box.
