What?!

On my travel journeys, I discovered this at the Chicago airport.

I was stunned. I have never seen this before.

Apparently, you was you hand over the sensor. Wait as new plastic comes out, then you do your business.

I wonder if it sanitizes the plastic or just uses new plastic... Hmmm

Most definitely a first for me! Certainly different from what I am used to!!

Have you seen these before? If so, where?
