Poland on Friday launched a smartphone app allowing people under a mandatory 14-day quarantine for coronavirus to send selfies to let authorities know they are indeed staying home.
"People in quarantine have a choice: either receive unexpected visits from the police, or download this app," Karol Manys, digital ministry spokesman, told AFP.
The "Home quarantine" app is intended for people undergoing the mandatory 14-day quarantine after returning from abroad, he said.
The app uses geolocation and facial recognition allowing quarantined users to check-in with authorities to confirm they are indeed staying at home as required.
Users first register a selfie through the app which then randomly requests more selfies throughout the day.
The app notifies police if users fail to respond within 20 minutes.
