+
+SwissCovid is the official contact tracing app of Switzerland. The app can be installed from the [App Store](https://apps.apple.com/ch/app/swisscovid/id1509275381) or the [Google Play Store](https://play.google.com/store/apps/details?id=ch.admin.bag.dp3t). The SwissCovid 2.0 app uses two types of contact tracing to prevent the spread of COVID-19.
+
+With proximity tracing close contacts are detected using the bluetooth technology. For this the [dp3t-sdk-backend](https://github.com/DP-3T/dp3t-sdk-backend), [DP3T iOS SDK](https://github.com/DP-3T/dp3t-sdk-ios) and [DP3T Android SDK](https://github.com/DP-3T/dp3t-sdk-android) are used that build on top of the Google & Apple Exposure Notifications. This feature is called SwissCovid encounters.
+
+With presence tracing people that are at the same venue at the same time are detected. For this the [swisscovid-cn-backend](https://github.com/SwissCovid/swisscovid-cn-backend), [CrowdNotifier iOS SDK](https://github.com/CrowdNotifier/crowdnotifier-sdk-ios) and [CrowdNotifier Android SDK](https://github.com/CrowdNotifier/crowdnotifier-sdk-android) are used that provide a secure, decentralized, privacy-preserving presence tracing system. This feature is called SwissCovid Check-in.
