Comment Not really new stuff... (Score 1) 66
I worked for a HMO from 2000s to 2010s. During my time there, we consolidated to a single building and were issued new badges that contained a RDIF that could be read remotely.
Every couple of minutes security would 'ping' the building and see where everyone was in the name of safety and security.
One day I had a gastro-issue and spent a lot of time in the restroom, and to my horror, there was a knock on my stall's door from security to see if I was okay.
After that, I would leave my badge at my desk while in the office.
So, basically not new technology, just using WiFi to do the checks vs RF.
