Many schools, universities and (shared-) offices use an RFID card, such as a student or company card, which they can use for access to many devices in the building. For example, opening the door, printing, getting lunch from the canteen, etc. Using the KUARIO app, these card(s) can be linked to your online credit. This means that you can pay/identify with both the KUARIO app and your card. Very convenient if you’ve left your mobile phone on your desk.
