NYC Metrocard Under a Microscope

Here are a few cool microscope images of a NYC Metrocard that I took the other day. What does this have to do with tools? An optical microscope is just one of the tools I use on a regular basis.

If you like these images, be sure to check out these electron microscope images I took of a #2-56 machine screw when familiarizing myself with a new scope’s operation.

In case you’re wondering, following is what a Metrocard looks like. These images were taken of the small white print at the bottom of the card.
