Javascript Barcode Reader

Description

The Barcode Reader Software Development Kit has been updated as a pure JavaScript API Edition, based on WebAssembly, to enable cross-browser and cross-platform online barcode scanning.

 

These features will empower developers with new conveniences for users. Users can scan barcodes in real-time from a browser using their smartphone without requiring an app download. There's also no need to capture an image and send it to a server for reading. This saves bandwidth and improves efficiency. In many cases, businesses use a browser-based system for pre-defined workflows. So, the JavaScript web API from the SDK will integrate easily into such workflows.

 

The JavaScript barcode reader supports real-time localization and decoding of various 1D and 2D barcodes from static images. It also supports decoding from a camera's video live stream whether from desktops, tablets, or mobile devices. This includes from device-independent bitmap (DIB) formats which can be obtained from cameras or scanners. Scanning can be accomplished for multiple barcodes at a time. The new barcode reader web API enables developers to implement browser-based barcode reading across varying computing devices.

 

Barcode Reader v6.4 also adds 2D barcode symbology support for Aztec Code, which is widely used in the transport business such as for airline tickets.

 

Dynamsoft Barcode Reader SDK enables application developers to efficiently embed barcode reading functionality in their web, desktop and mobile applications using just a few lines of code. This removes months of additional work and costs associated with coding from scratch. With the SDK, end users can decode barcodes from various image file formats (BMP, JPG, PNG, PDF, and TIFF) or video live streams. This includes black/white, color or grayscale images.

 

Supported developer platforms include Windows (C, C++, .NET, JavaScript), Linux (C/C++), iOS (Objective-C and Swift), and Android (Java). Supported 1D barcodes (linear barcodes) include Code 39, Code 128, Code 93, Codabar, Interleaved 2 of 5, Industrial 2 of 5, EAN-13, EAN-8, UPC-A, UPC-E. Supported 2D barcodes include QR code, Data Matrix, PDF417, and now Aztec Code. There are also Mac and Raspberry Pi editions available as Labs projects.

 

Barcode reading results include format, text, bytes, angle, module size, the name of the document including the barcode, page number, region name, and the coordinates of the barcode vertices.

 

Dynamsoft's Barcode Reader SDK provides rich code samples. It is backed by technical support channels that include an online knowledge base, e-mail, live chat, phone and more. It is now available for download from the Dynamsoft website. Developers can also try an online demo and download trial versions from the website product page.
