Open questions

Who created such device? Casinos? Level of sophistication means either stolen tech or large underground market

Who is ripping who? Where is this thing actively used? Need detection means and field study!

Where is the ink is coming from? You can’t buy it easily - only for secure marking of docs

ly.tl/poker

Takeway

James Bond devices exist! They are hard to find but reality match fiction

Crimeware can be super sophisticated While NSA have cool tools, the crime mob does too!

A very diverse skillset is required to tackle this type of device infiltration, hardware analysis, software analysis, RF analysis, Vision Alg.
