I'm thinking about making a deck of cards using these markings, to make the game a bit more interactive and immersive for the players.

When the sheltered communities of the underground emerged after a century of self imposed exile, they needed a quick and secure method for marking territory to one another. Unable (or unwilling) to use their high tech gadgets, except for short bursts of computing power, they've taken to spraying an ancient form of coding on the roads, just beyond the outskirts of settlements. When one of the sheltered approaches a settlement that has been visited before, they pull out a handheld computer, activate it for a few seconds to analyse the markings on the ground and then determine if it is safe to proceed into town.
