Pan-European Privacy-Preserving Proximity Tracing (PEPP-PT) makes it possible to interrupt new chains of SARS-CoV-2 transmission rapidly and effectively by informing potentially exposed people. We are a large and inclusive European team. It provides standards, technology, and services to countries and developers. It embraces a fully privacy-preserving approach. It is built on well-tested, fully implemented proximity measurement and scalable backend service. It enables tracing of infection chains across national borders.
