China is prototyping new genetic ID cards.
This color genotype ID card, about twice the size of ordinary ID card, has on it data such as photo, birth date, nationality and gender. In particular it is marked with 18 internationally used genetic locus which are chosen from the long chain of human cytogenetic information carrier DNA molecules. In the combination of the 18 genetic locus, with the exception of one egg giving birth to twins, it is difficult for one to find out such a circumstance wherein two persons out of 10 billion people are completely the same.
