Under our clothes, each of us wore short-sleeved white shirts emblazoned with a passable imitation of the Medf-Carro crest, as well as plain black trousers. Fake ID badges hung from the front pockets of the shirts. The "uniforms" wouldn’t stand up to careful scrutiny, and the magnetic datastrip on the ID badges didn’t hold any information and wouldn’t pass a scanner check. But if Fede succeeded in getting us into the first-aid rooms of the tlachtli, we wouldn’t have to worry about that.
