SAFEDI

SAFEDI is a lightweight (0.03 lbs), coinsized clip that is worn on the upper part of the body, close to  to the facial area which is particularly susceptible to infections. Should the minimum distance not be maintained, SAFEDI starts emitting visual and optional auditory warning signals and the respective SAFEDI-ID is recorded into a close contact tracing journal until the minimum distance is reestablished again. Thanks to its constant visibility, SAFEDI reminds everyone to keep a safe distance.
