British Identity Card: The Commonwealth issued the compulsory identity card for the first time during World War I, but it was cancelled in 19 19. The identity card was reintroduced in World War II, but it was abolished in 1952 seven years after the end of the war, because public anger reached its climax in the case of Wilcock v. macor, in which Clarence Henry Wilcock refused to show his identity card after being stopped by the police for illegal driving. Although he lost the lawsuit, the court unanimously agreed with him that the existence of the ID card was inappropriate. Nevertheless, some ministers of state suggested reintroducing the identity card system. Under various pretexts, in 2003, David Blunkett, then Minister of State, indicated that the British government intended to launch a domestic ID card scheme based on biotechnology, and at the same time use a database to record the resident population, and make it mandatory before 20 13. The State Office believes that such an ID card will frustrate the activities of international terrorists, and 35% of terrorists travel under false identities. Recently, the government also claimed that this kind of ID card will help prevent illegal immigrants, "healthy travel", defrauding allowances and stealing identities, and biological passports will also make it easier for British nationals to travel to the United States. American identity card: At present, there is no real national identity card in the United States, because there is no such federal agency in China that has enough judicial power to issue identity cards to all American citizens. All the legislatures have tried to establish such an institution, but they have failed, mainly because of the strong opposition of liberals and conservative politicians, who regard this national identity card as a symbol of totalitarian society. However, after the establishment of the Social Security Administration in 1930s, the federal government stipulated that all legal citizens and residents must hold social security numbers. DNI-e sample Spain (Documenta Nacional de Identidad) is a country that implements compulsory ID cards, which may not take effect until a certain age. Note: The word "compulsory" in the clause may have different meanings in different countries. Usually, if you don't have an ID card, you may be given a ticket, or in some cases, you will be detained until your identity is confirmed. In fact, random management is rare, except in totalitarian countries.

Identity cards that are not used to prove citizenship Some enterprises or government departments issue "identity cards" (qualification certificates) for certain social purposes. These "identity cards" can be used to prove some qualifications. For example, in Britain, taxi drivers must carry "ID cards".
