Each signage gets attached an NFC tag and/or a QR code. By using the smartphone to tap the NFC tag or scan the QR code, we get provided limitless possibilities of services.
All functions behind the NFC tag and QR code are managed digitally. For this purpose, we have developed haarn.io - service software, that allows everybody to easily manage and present the content you want to provide.
If not attached to the original signage a special designed sign can be nearby presented.
Therefore we have created the DesignTag®, a sign that tells by it looks the function it stands for
