To foster widespread adoption, established tracing protocols focus on smartphone users. As a result, user groups who cannot afford a compatible smartphone cannot carry it continuously are left out. This work introduces the Contact Tracing Wristband (CWB) and its integration into Google and Apple’s Exposure Notification protocol. The wristband’s low-cost and versatility bring tracing to additional users and thus enhance the efficacy of tracing.enTechnology::600: TechnologyConference PaperConference Paper
