We hear about social distancing a lot these days, so it is no wonder that a bunch of companies are working on products that can help with that. Take the Safe Spacer for instance: it is a wearable social distance monitor that helps keep people safe at their workplace. It can sense other devices within 6ft to alert the wearer when they are too close.
The device delivers vibration and audio feedback. Each has a unique ID tag and built-in memory for unintentional contact tracing. The companion iOS/Android app lets you configure the alarms and set custom distance/alert thresholds.
