Identity (ID) cards are known for their utility and integrity, which led to the adoption of its use by many countries all over the world. Some countries even have national IDs, which are officially released and which use is mandatory to all who sojourn in said territories. Examples of these countries that have a national ID system are France, Germany, Belgium, Luxemburg, Spain, and Greece. On the other hand, many developed countries such as Australia, Sweden, Canada, and the United States, did not adopt such an identification system. National ID systems are established to serve two main purposes. The first one is to increase the police powers of the State. Consequently, ID cards can help the State reduce crime rate, conduct social engineering, and reduce the threat of insurgents or political extremists. The second purpose is to establish a comprehensive and useful administration of government services. The technology behind modern ID systems, such as the magnetic stripes and the microprocessor technology, ID cards offer a valuable towards the more efficient delivery of government services. However, while it appears that having a National ID system may offer many advantages, such a system could also pave the way for abuses on civil rights, invasion of privacy, and discrimination. In addition, the establishment of such a comprehensive registration system, would entail a huge amount in costs, which is an important consideration to make. All of these considerations should be weighed in order to reach at an intelligent decision on the issue of whether citizens of the United States should be required to carry National IDs.
