The chapter opens with a discussion of the cell phone portability system, which allows a person's cell phone number to be transferred from one cell phone company to another. For example, if you're in high school and have a new name, your old name is automatically transferred to another high school. If you get a new job and have to keep the same hairstyle, it's like you've been carrying over the same dream from high school all the way up to college. This is a gross system, but it works, because people don't have to think about changing their name when they change jobs. It's also useful when you want to solve a crime, because the person who ran the car that was involved in the crime has a memory of the license plate that was used to get into the car, which is then transferred to your new cell phone. The chapter ends with a soliloquy about the importance of having a clean slate in life. He says that he'll start with a "clean slate" in his next life, because there's "a portability system" in the world that will allow him to go back and forth between his old life and his new life.
