Iris Recognition Immigration System (IRIS) was an initiative, launched in 2004, to provide automated clearance through UK immigration for certain frequent travellers. It functioned in "one-to-all" identification mode, searching a large database of some million enrolled frequent travellers to see if anyone matched the presenting iris. The passenger was not asked to assert any identity, e.g. by presenting a Passport or ID card which would then require only a "one-to-one" verification test against that single enrolled identity. Thus IRIS exploited the great robustness of iris recognition against making False Matches, since (unlike weak biometrics such as face recognition) it could survive the vast number of opportunities to make False Matches when searching a large database, instead of only needing to test just a single asserted identity. It was decommissioned in September 2013 in favour of e-passport entry using biometric data stored on the e-passport chip, which requires only a single asserted identity to be tested and thus could function using weaker biometrics in the simple "one-to-one" verification mode.
IRIS relied on biometric technology to authenticate identity and was part of the e-borders initiative of the UK Government. The main factor behind the decision to decommission IRIS was the cost of staffing the enrolment offices in airport terminals, whereas face recognition only required submitting a Passport-type photograph acquired in a photo-booth without the need for personal presentation to airport enrolment staff.
The entire scheme, including cost of scrappage, cost £11.8 million. [1]
Enrolled passengers could enter the UK through a special automated immigration control barrier incorporating an iris recognition camera. These barriers were located in certain Immigration Arrival Halls and form part of Immigration and Passport Control.
Enrolment took place in the airport departure lounge where an Immigration Officer assesses eligibility and enrols qualifying persons. Those who qualified to participate in the scheme had both their eyes photographed in order to capture their iris patterns. This data was then stored securely alongside their personal details.
Originally IRIS was rolled out at London Heathrow, London Gatwick, Birmingham and Manchester in 2004 for an intended deployment period of five years. [2] As of February 2013, IRIS was only available at Heathrow Terminals 3 and 5, [3] all other barriers being decommissioned. These last operational barriers were decommissioned on 15 and 16 September 2013, respectively, after the original deployment plan for five years had been doubled to nearly ten years. [4]
Following travellers were eligible to enrol:
The Singapore passport is a passport issued to citizens of the Republic of Singapore. It enables the bearer to exit and re-enter Singapore freely; travel to and from other countries in accordance with visa requirements; facilitates the process of securing assistance from Singapore consular officials abroad, if necessary; and requests protection for the bearer while abroad.
Global Entry is a program of the U.S. Customs and Border Protection service that allows pre-approved, low-risk travelers to receive expedited clearance upon arrival into the United States through automatic kiosks at select airports and via the SENTRI and NEXUS lanes by land and sea. As of May 4, 2018, Global Entry was available at 53 U.S. airports and 15 preclearance locations. By April 2018 more than five million people were enrolled in Global Entry and approximately 50,000 new applications for the program were being filed each month.

The visa policy of Singapore deals with the requirements a traveller must meet to enter Singapore. A foreign national, depending on their country of origin, must meet certain requirements to obtain a visa, which is a permit to travel, to enter and remain in the country. A visa may also entitle the visa holder to other privileges, such as a right to work, study, etc. and may be subject to conditions.
Biometrics refers to the automated recognition of individuals based on their biological and behavioral characteristics, not to be confused with statistical biometrics; which is used to analyse data in the biological sciences. Biometrics for the purposes of identification may involve DNA matching, facial recognition, fingerprints, retina and iris scanning, voice analysis, handwriting, gait, and even body odor.
ePassport gates are automated self-service barriers operated by the UK Border Force and located at immigration checkpoints in arrival halls in some airports across the UK and at the juxtaposed controls in international railway terminals abroad, offering an alternative to using desks staffed by immigration officers. The gates use facial recognition technology to verify the traveller's identity against the data stored in the chip in their biometric passport, as well as run the data against numerous databases to determine if the traveller is a security risk.
Visa requirements for Liechtenstein citizens are administrative entry restrictions by the authorities of other states placed on citizens of Liechtenstein. As of March 2023, Liechtenstein citizens had visa-free or visa on arrival access to 180 countries and territories, ranking the Liechtenstein passport 12th in terms of travel freedom overall, and the lowest of the EFTA member states, according to the Henley Passport Index.
Visa requirements for Zimbabwean citizens are administrative entry restrictions by the authorities of other states placed on citizens of Zimbabwe. As of 2 July 2019, Zimbabwean citizens had visa-free or visa on arrival access to 64 countries and territories, ranking the Zimbabwean passport 80th in terms of travel freedom according to the Henley Passport Index.

Many countries have entry restrictions on foreigners that go beyond the common requirement of having either a valid visa or a visa exemption. Such restrictions may be health related or impose additional documentation requirements on certain classes of people for diplomatic or political purposes.
PARAFE is a passport verification and border control system deployed in France and operated by French border guards. PARAFE consists of automated self-service gates, located at certain French border checkpoints and offer a faster alternative to manual checks at desks staffed by border guards. The gates use facial recognition technology to verify the user's identity against the data stored in the chip in their biometric passport.
Automated border control systems (ABC) or eGates are automated self-service barriers which use data stored in a chip in biometric passports along with a photo or fingerprint taken at the time of entering the eGates to verify the passport holder's identity. Travellers undergo biometric verification using facial or iris recognition, fingerprints, or a combination of modalities. After the identification process is complete and the passport holder's identity is verified, a physical barrier such as a gate or turnstile opens to permit passage. If the passport holder's identification is not verified or if the system malfunctions, then the gate or turnstile does not open and an immigration officer will meet the person. E-gates came about in the early 2000s as an automated method of reading the then-newly ICAO mandated e-passports.
