HEY - I pushed the "button" to cross the street & realized "it's swiping my prints!"

The "button" one "pushes" to cross the street at busy intersections at crowded streets is no button at all.

It's some kind of infrared device that scans or senses the person's finger, then makes a "blip" sound.

We've all used them.

I think it's reading fingerprints! Big brother, the beast...gathering more info on us.

Possible. Maybe even plausible.
