The biometric system can also translate information in a chip on a passport and compare this with facial features using UV and infrared light to see whether there are any differences to identify fake passports.
In a span of just three days, the system has helped police arrest 8,000 illegal immigrants, fake passport holders, overstaying travellers, and legal offenders on arrest warrants.
Recently, Thananat Siripiyaporn, an infamous billionaire groom who left his bride without allegedly paying wedding bills, was arrested at Don Mueang Airport after his arrival from Hong Kong. He has also been a fugitive in a fraudulent check charge since 1991.
A biometrics system is primarily a body and behaviour observation system to identify physiological characteristics by using fingerprint, palm print, voice, face recognition, DNA, iris recognition, retina, and signatures, all of which have been used by the US Central Intelligence Agency and the Federal Bureau of Investigation for the past 25 years.
However, the proficiency of this system depends on the commitment and collaboration of responsible offices including the police, immigration office, and the Justice Department to update and share their databases to make sure the system can identify a suspect even after he/she changes identity.
