Genetic individuality. Conceptual computer artwork showing a DNA (deoxyribonucleic acid) helix over a barcode. DNA carries genetic information and each person's genetic information is unique (except in the case of identical twins). Therefore, genetic information could be included in ID cards or biometric passports, helping to reduce crime or fraud. The sort of information stored in the card or passport would include details of fingerprints or an iris scan. However, there are concerns regarding the cost of issuing ID cards and the possible infringement of civil liberties.
