Identity markers in the Corporation Rim usually had a lot of information on the bearer, but these were temporaries meant for travelers from outside the Rim. They had a string of numbers from a non-corporate political entity authorizing travel, place of origin, and a name. Obviously this was why Wilken and Gerth had them, so they could switch identities at need. Corporate political entities are more interested in keeping track of their own humans than anybody else’s. I had seen on the media that travel was easier for non-citizens inside the Corporation Rim than citizens, sub-citizens, and all the other categories each different political entity had to keep track of their humans. (It could be worse. At least humans could cut out their ID markers; I had corporate logos etched onto parts of me I couldn’t get rid of.)
