Effective quarantine of the infected people is the crucial step to curb the spread of COVID-19. IoT can help ensure that a person is following the quarantine rules. Some countries such as Russia, Poland, and Singapore are using IoT and GPS enabled apps to track the movement of people. People are given wrist-bands with unique QR code on them. People from the dedicated app have to scan the QR code which is used to track their movements. The basic technology used is Geofencing, which is created using cellular networks, RFID, GPS, Wi-Fi, and Bluetooth signals.
