Legal identity is a document which declares to any party one is interacting with who you are. Over the past decade, many countries have mandated the possession of a government-issued identity; as it has been recognised that the ability to prove one’s identity has become an important factor for participation in social, political, economic, and cultural life.

The inception of identity cards

The contemporary era of ID cards started during World War II.
The United Kingdom lawmakers passed the National Registry Act in 1938, which made the possession of identity cards mandatory for all the residents.
In 1938, The German government also instituted an ID system.
The Vichy government in France instituted an ID system as well as in Greece and Poland in 1940.
The now-

21st-century digital technologies, like biometrics and other forms, are providing a unique opportunity to transition from the traditional, paper-based approaches to build a robust and efficient identification system at a scale previously not as achievable.

According to research company Acuity Market Intelligence, the number of electronic National ID cards in circulation will reach 3.6 billion citizens by 2021.

According to Acuity Principal and biometrics and secure document market expert, Maxine Most, “In addition to the 3.4 billion chip-based National eID’s issued between 2014 and 2018, another 300 million National ID cards will integrate biometrics into non-chip-based card programs.”

Now most countries, a government-issued national identity card is the main program that is being used for both identification verification and at least one functional authentication purpose.
