Because of the use of an advanced biometric system at 16 international airports in Thailand, more than 1,000 people were found on the blacklists and watch lists, over 45,000 who overstayed, and about 700 who have arrest warrants, Immigration Police chief Lt-General Sompong Chingduang said on Monday.
The said 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, reported The Nation.
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, the report added.
A biometric 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.
