I remember a doc/5 minutes segment 3-5 years ago showing employees with RFID chip under the skin to reduce friction when opening doors leading to restricted access and give access to printers.

And now that I think about it there's a comment of mine somewhere with a link to a line of connected motion sensors mounted in office chairs to "optimize lightning costs".

edit: found it again:

Identified needs – why to focus on office chair monitoring?

    Data-driven managers love to monitor home officing, track work hours, save space and costs incurred by unoccupied desks when employees work away from an office or on flexible schedules
    Companies are willing to avoid wasting money on lighting, heating, and cooling
    Facility companies want to optimize cleaning services
    There is a shift to working hubs, hot seats and a need for shared space utilization
