What is "j-bis"

The J-BIS Biounit is an immigration control system that was introduced into Japanese airports. It is a machine that is located at the immigration booth. When a person who wishes to enter the country and applies for disembarkation, fingerprints of both index fingers are collected along with a photograph. At the same time, the person is checked against immigration office lists, and criminals, people who were previously deported, and other punished foreigners are prevented from entering the country. On November 20, 2007, Narita Airport, Kansai International Airport, and Chūbu Centrair International Airport had the system, with plans to roll out the system to the 27 airports and 126 harbors in the country.
