In order to contain the spread of the SARS-CoV-2 virus and reduce the risk of contagion in indoor spaces (schools, universities, hospitals, offices, factories...) it is advisable to adopt behaviors that guarantee distance between people, avoiding gatherings .
IoT technologies can be a useful aid, through the adoption of personal devices capable of monitoring and tracking contact events and alerting in alert situations: SafeX Tracer is the wearable device that increases the safety of employees and visitors by controlling the distance between operators in the workplace (social distancing) and contact tracing (contact tracing) . It can also be used as a personal identification device, integrating it into company location and access control systems.
