![]() Quickly scan a selected area with the keyboard shortcut CMD+1 (also available from the top menu) Automatic copy to clipboard (enabled in preferences ) Export scanned QR codes / barcodes as CSV text Full-screen barcode scanning (File-> Full-Screen scan, App Icon-> Full-Screen scan) Scan your clipboard for a QR code / barcode Drag & Drop on the app icon to scan a QR code / barcode Code Scanner - scans QR codes (screen or camera*), scans other 2D barcodes (screen only) Works with iPhone & webcams (EpocCam.) and it natively runs on the new M1 processors. Capture QR codes like you would do on a phone. Use iPhone or webcam (EpocCam.) to capture QR codes. Capture QR codes like you would do on phone. This can be useful for determining whether to offer the QR web cam scanning functionality to a user.The most simple & easy QR Reader. This library provides a utility method for checking whether the device has a camera. If no QR code could be read, scanImage throws. log ( 'decoded qr code:', result ), to enable the new api and get the detailed scan result. const qrScanner = new QrScanner ( videoElem, result => console. To enforce the use of the new api with detailed scan results, call the constructor with an options object, see below. Create HTMLĬreate a element where the web cam video stream should get rendered: ![]() Especially if you want to scan from the device's camera, camera support by the browser is the stricter restriction. You will likely not need to use the legacy build though, as general browser support is already very good for the regular build. Note, that the legacy build is larger as it includes some polyfills and, to support browsers that don't support dynamic imports, inlines the worker script which however would be needed to be loaded in legacy browsers anyway. It's a UMD build and can be used as a replacement for, see above. ![]() If you need to support old browsers, you can use, which is ECMAScript 2015 (ES6) compatible. This library uses ECMAScript 2017 features like async functions. The development of this library is sponsored by nimiq, world's first browser based blockchain.Ĭonst QrScanner = require ( 'qr-scanner' ) // if installed via package const QrScanner = require ( 'path/to/' ) // if not installed via package // do something with QrScanner The library supports scanning a continuous video stream from a web cam as well as scanning of single images. Also the other library oftentimes misreads the content of QR codes, while for this project no misreads occurred in the benchmarking.
