QR Codes are a very popular method of transmitting data to users on the go. This stack allows you to easily link to a URL, phone, GPS, email, contact vcard and more. All QR codes are generated dynamically as SVGs in order to ensure high definition.
All modern mobile devices with a camera should support scanning a QR Code. If you open your camera app and point the camera to the QR Code, you should get a notification on your device to launch the data linked to the QR Code.
The QR Code stack will also link to the stored data as well. You can simply clink on the QR Code just as if it was a link.
