Using Scanova, you can create two types of QR Codes - Dynamic and Static.
Dynamic QR Codes contain only URLs. You can edit the target URLs (content you want to show) at anytime without the need to create a new QR Code. They are also trackable and you can see scan analytics in your account.
Static QR Codes can contain information such as URLs, text, contact information, and Wifi password. They are permanent and the data is encoded in the QR Code itself - just like a barcode. You will not be able to edit content or track scanning activity.
