Static QR Code
The information encoded in static QR codes are fixed. The destination/data is stored directly in the QR Code graphic (hence QR codes are also getting larger and form a more complex pattern if there is more data to store). Therefore, the stored destination/data cannot be changed. Any typo in an already printed QR code cannot be changed, as with any other printed material.
Dynamic QR Code
A Short URL is placed into the QR code which then transparently re-directs the user to the intended destination. The destination of a dynamic QR code can be changed at any time and as often as you want – even if your marketing material has already been printed. This will save reprinting costs, effort and enable you to respond to any changes in the campaign as quickly as possible.
