System Identification Numbers (SINs)

People are identified by many identifiers in many systems, but the System Identification Number is the gold standard. Every SIN is tied to at least a name, a picture, and a fingerprint. While every SIN holder has been fingerprinted, many registrations include retinal scans, limited DNA profiles, and voice samples. Maintained by Global Systems Registries, the SIN is used by most governments and corporations to identify citizens and employees.

GSR provides for the vast majority of identification-check services throughout the system. With even a basic scanner, and a service contact, GSR can identify whether a particular subject's biometrics match a provided SIN. Authorized customizers, such as law enforcement agencies, can retrieve a SIN based on provided biometrics.

Many older SIN holders have a UV-reactive barcode tattoo on their wrist of their number, with younger citizens often relying solely on embedded short-range radio transmitters.
