Today, in a private meeting, I met the CEO of a company that offers a security wearable that provides instant visual verification of authorized presence.
This wearable that looks like a case of your existing ID card emits a continuously changing random sequence of colors that will make a visual difference for authorized and unauthorized cardholders.
This also works effectively with the location that you cannot install Access Control technology.
I'm excited about this product, and I have many use cases in my mind, but I cannot write about it here. I have to limit sharing information publicly related to my work.
