The Human Pin Code refers to a system created by Douglas Forbes. It is based on the scientific and mathematical relationship between numbers and the personality of human beings based on his date of birth. The system has its basis in Physics and Atomic theory rather than Numerology. He claims to have been developed a mathematical system that reads a personality, characteristics and even life cycle of a person with 99% accuracy. However, the effectiveness of this system has yet to be verified as Forbes has never made public his scientific research on the subject neither has he demonstrated it in public.
