It is free of charge and does an excellent job of recognizing even blurry images. This free barcode scanner API for web applications is currently available on all Chromium-based browsers. In general, the tool can be used to recognize any images and even faces, and there is a separate Barcode Detection API for barcodes, made on the same platform. How does it work? This is an API developed by Mozilla that allows you to access your computer's computing resources through a browser. Pros: high percentage of recognition, flexibility, huge customization optionsĬons: development time, need for further support, cost Shape Detection API 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. Barcodes and QR codes are almost everywhere.
