Other identification methods include vain patterns or their signatures, recognizing heart beats, 3d face recognition.
Iris patterns a unique to each individual as our facial details. Currently we are in the phase where the database is been created. At present, it is used mostly in airports and hospitals however I think it will be a gradual rollout of the biometrics system.
In few years time, I think people would start using biometrics systems just beyond criminal justice system.
Handprints are also different for each individual along side of the figure prints. The machine records the vain and arteries in your hand that is another means of confirming you are who you say you are. The latest recognition tool that is in research is to identify individual by recognizing their walk pattern
