A South Korean woman barred from entering Japan last year has reportedly passed through its immigration screening system by using tape on her fingers to fool a fingerprint reading machine.
The biometric system was installed in 30 airports in 2007 to improve security and prevent terrorists from entering into Japan, the Yomiuri Shimbun newspaper said.
The woman, who has a deportation record, told investigators that she placed special tapes on her fingers to pass through a fingerprint reader, according to Kyodo News.
Japan spent more than Y4 billion ($A64 million) to install the system, which reads the index fingerprints of visitors and instantly cross-checks them with a database of international fugitives and foreigners with deportation records, the Yomiuri Shimbun said.
The South Korean woman was deported in July 2007 for illegally staying in Japan after she worked as a bar hostess in Nagano in central Japan, Kyodo said, citing justice ministry sources.
She was not allowed to re-enter Japan for five years after deportation but the Tokyo immigration bureau found her in August 2008 again in Nagano, Kyodo said.
