A discussion about QR codes on dice turned into this.  A D6 with a QR code on each side that will take you to a wikipedia page indicating the value,.  This is an objectively-stupid die and nobody should actually print it, let alone use it for actual gaming purposes.

If you are foolish enough to print it, you will almost certainly need to paint it in order to get enough contrast on the QR code for your phone to pick it up.
