Because there is free QR code software to read QR codes for almost every smartphone with a camera (e.g. The most prominent use-case for QR codes is the area of mobile marketing. The high data density compared to simple barcodes, the licensing policy of the QR developer / creator Denso Wave plus the wide availability of reading software has helped the QR code to establish itself and pushed technically comparable 2D codes out of the market (see “ What is a QR code” for more information on this topic).

To create one, the information gets encoded according to ISO/IEC 18004:2006 by a QR generator like ours. However, QR graphics are able to store much more data, they can include over 3000 characters on a very small space. used on the product packaging at the grocery store.

Just encode them with our QR code generator to easily transfer the data to mobile devices.ĢD barcodes (a group of barcodes the QR code belongs to) are comparable to common, one-dimensional bar codes as they are e.g. But you can also work with other texts and data, such as advertising messages, telephone numbers and even entire business cards in vCard format. Because QR codes make it so easy to transfer a web link to a mobile phone, they provide a significantly lower barrier to visit a site with a smart phone. QR codes are the way to go to create a link between the real world products (tagged with the QR code) and the Internet.

Of course, you can place and use the QR graphic on leaflets, posters, business cards or other products without any costs / for free (including commercial use). You can also embed the QR code directly on your own website and use it, just have a look at the code offered by the “Embed” button.

Just click on the “Download” button to get the created QR code image then (the image is available as EPS or SVG vector graphic, as well as high-resolution PNG, GIF or JPEG raster graphics format). The QR code will be generated automatically as you type. * As second parameter the callback that expects the data from the QRCode as first parameter.Just enter your text, your URL, a SMS or vCard contact information. * The function decodeImageFromBase64 expects as first parameter a base64 string from a QRCode.

The following snippet, shows the most basic usage in a simple html snippet (feel free to download and test it locally). Implementationīasically, to use the library you'll need to use 2 lines, set a callback that receives the decoded data and provide the base64 image as first parameter in the decode function: // set the callback that receives the decoded content as the tasks is async You can download (or clone) its source code in the official repository in Github here. The source code itself is based in 17 different JS files (that needs obviously to be loaded in your html document using the script tag). This library is a JavaScript QRCode reader implementation for HTML5 created by Lazar Laszlo. To achieve our goal, we are going to depend on the jsqrcode library.

In this article, you'll learn how to scan a QR Code from its base64 value easily using jsqrcode. Yep, they're normally scanned by someone with a smartphone ,but thanks to jsqrcode, we can achieve the scanning process without a camera and decode the information from plain (PNG or JPEG) images (in base64 format to be more specific and to increase accuracy) in case you ever need such a feature in any of your crazy company (or own) projects. A QR code is short and sweet (besides quite useful) for a quick response (they can be read quickly by a smartphone).
