Works set in the future or depicting organisations with access to advanced technology often show that characters have been injected with microchips to identify or track them. This can show technological advancement or a lack of privacy for the protagonists. In darker works, a character may not recall being "chipped" and be alarmed when they find one in their body, raising questions about who is tracking them and how it was installed. Note that technologies that aren't used for tracking or identification, such as the head jacks in The Matrix, don't count as examples. Compare Big Brother Is Watching, Restraining Bolt, The Schizophrenia Conspiracy.
