A visa is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or leave its territory. Visas typically include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual can work in the country in question. Visas are associated with the request for permission to enter a territory and thus are, in most countries, distinct from actual formal permission for an alien to enter and remain in the country. In each instance, a visa is subject to entry permission by an immigration official at the time of actual entry and can be revoked at any time. Visa evidence most commonly takes the form of a sticker endorsed in the applicant's passport or other travel document but may also exist electronically. Some countries no longer issue physical visa evidence, instead recording details only in immigration databases.
A biometric passport is a traditional passport that has an embedded electronic microprocessor chip, which contains biometric information that can be used to authenticate the identity of the passport holder. It uses contactless smart card technology, including a microprocessor chip and antenna embedded in the front or back cover, or centre page, of the passport. The passport's critical information is printed on the data page of the passport, repeated on the machine readable lines and stored in the chip. Public key infrastructure (PKI) is used to authenticate the data stored electronically in the passport chip, supposedly making it expensive and difficult to forge when all security mechanisms are fully and correctly implemented.
