Now let’s try the app. The less you wait, the more you’ll be demanding from the user’s device, so be mindful. The more you wait for the next scan, the slower it’ll be. You can set this to something else to see what happens. If we can’t find anything, the error we defined will be caught and we’ll call a setTimeout to scan in 300 milliseconds. We run the decode function from the qrcode library, which will look for a canvas with an ID of "qr-canvas" and scan its contents. Add the following to your css file: html We just want some basic styles for this sample app. Now we want to create the style.css file within the src folder. Adding StylesĪdd the stylesheet to the head of our HTML: We’ll create it later, but first we’ll improve the look of our app. Outside the container div we’re including the qrCodeScanner.js file. Add the following to your body tag: QR Code Scanner Data: Īs you can see, we have a wrapper container with a title, the QR icon image wrapped in an a tag, a canvas and a div where we’ll show the result of the scan. We’ll need some very simple HTML for this project. Let’s begin by creating an index.html file. We’re not going to build that ourselves, because there are some great libraries out there doing this for us, so we don’t need to reinvent the wheel for our current purposes. Fun2D QR Code reader SDK is available for your custom Android APP (see for more detials).Our QR code reader will need some HTML and JavaScript but most importantly, a JavaScript library capable of interpreting the QR code. Logo QR Barcode Scanner was built with Funcode Technology's Fun2D QR Code reader SDK. ![]() Other features: Very small APP size to save your space, friendly portrait scanning, interactive scanning indicators, support low quality QR Code like small QR Code on bottle cap (demo video - ), UPS/DHL package tracking support, you can SHARE the scanning results, can be used as "magnifier with light".
