While there is no mandatory identity card in India, the Aadhaar card, a multi-purpose national identity card, carrying 16 personal details and a unique identification number, has been available to all citizens since 2007. The card contains a photograph, full name, date of birth, and a unique, randomly generated 12-digit National Identification Number. However, the card itself is rarely required as proof, the number or a copy of the card being sufficient. The card has a SCOSTA QR code embedded on the card, through which all the details on the card are accessible. In addition to Aadhaar, PAN cards, ration cards, voter cards and driving licences are also used. These may be issued by either the government of India or the government of any state, and are valid throughout the nation. The Indian passport may also be used.
