Identity document

An identity document (abbreviated as ID) is a document proving a person's identity. If the identity document is a plastic card it is called an identity card (abbreviated as IC or ID card). When the identity document incorporates a photographic portrait, it is called a photo ID. In some countries, identity documents may be compulsory to have or carry.
