At least one school in our area is using Bluetooth technology to monitor students and alert them if they've been in contact with someone with COVID-19.
When someone comes down with the virus, health officials try to figure out who those people came into close contact with so others can be warned, tested and isolated to slow the spread of the virus.
As schools reopen across the nation, contact tracing is largely done by asking the infected person who they spent time around over the last two weeks.
It's a process that relies on memory, but it doesn't have to.

A company called ReturnSafe has a system in place that uses Bluetooth lanyards to monitor a student's progress throughout a school.
If the student comes down with COVID-19, the data collected by the system can be used to figure out who may have been exposed to. The process of isolating close contacts can happen quickly and more accurately than relying on memory.
"With these lanyards, it makes the whole process completely automated," said Jikku Venkat with ReturnSafe.
