To open & close the lockers, users only need the KUARIO mobile app. With the KUARIO mobile app, users scan a QR code on the locker display, which opens an assigned locker. Users can also link an RFID card to the KUARIO mobile app, so they can always get access to the locker when their smartphone is not available.

Apart from opening a locker with the KUARIO mobile app, this app offers many other benefits. For example, with the KUARIO mobile app it is also possible to pay for vending machines, coffee machines, print jobs, or in the canteen. Guest users can also create an account to pay for all unattended self-service devices.
