"At its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we can't predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe."
- John Brunner

Automated DNA Typing  
  A device that takes quick samples of DNA and compares each sample to a database.  

In the future society depicted in the film, employment is strictly controlled. Certain positions have absolute genetic requirements.

In fact, for particular jobs, you must prove every day that you are who you say you are. And you must prove that you are genetically pure and worthy - every day. To make sure, you give a small blood sample taken by an automated DNA typing machine.

DNA typing (also called genetic fingerprinting, DNA testing, DNA typing, and DNA profiling) was invented by Sir Alec Jeffreys at the University of Leicester in 1985. Since human beings have almost all genetic material in common with each other, genetic fingerprinting exploits highly variable repeating sequences called minisatellites. Two unrelated humans will be unlikely to have different numbers of minisatellites at a given locus.

At present, DNA typing can be (to some extent) automated, but it is too time-consuming to provide a good access-control technology as shown in the film.
