““The crew advised us to learn the locator and security identifier methods that were so common on Earth. In most nations we would have no choice, but in a few we could choose to abstain. When I asked Will Nelson why those systems had been developed, he told me that the coded anklets had been introduced as a more convenient version of credit cards and had soon become status symbols. Someone equipped with an anklet could receive phone calls anywhere and could pick up merchandise in a store and walk out with it, free of the delay of waiting in a checkout line. As another visible sign of special privilege, the anklet wearer could walk directly on board a plane without stopping either at a ticket counter or a gate. It was only some time later, Nelson told me, that the records of position made possible by the anklets became legal evidence in courts of law. His advice to me was direct: unless I just couldn't stand the notion, I would be a lot better off letting the immigration guards at Freeport Seven put an anklet on me. If I didn't, I would be annoyed by time-wasting delays at every national border, and I'd be hassled at every residential town, museum, and shopping enclave.””
