Is there a provision to add more than one kiosk device?

Yes, there is, and you can add the kiosk devices from the Web Dashboard.

There are several reasons why a workplace may require multiple kiosks. Companies with large premises often install separate kiosks for different departments, and many even have individual kiosks for punching IN and OUT. 

Multiple kiosks also help speed up attendance marking when there are many staff members.

 

In Truein Web Dashboard: 

Web Dashboard: Settings > Kiosk > Kiosk Settings > Add Kiosk (+) > Enter Kiosk Name and select the required options> Click Add

Now, you can start using this kiosk by entering the respective Activation Key generated for it.
