Foreigners arriving in Ukraine are subject to biometric verification as of 1 January 2018, the press service of the State Border Service has said.
Under the new rules, citizens of 70 risk countries, including Russia, will have five fingers of their right hand scanned upon arrival. Other foreigners may also be required to undergo finger scanning.
Data sets will be compared if a foreigner visits the country again. If they do not match, such persons will have to undergo additional checks.
During border passport control, foreigners will also be checked against Interpol's databases.
Over 2,700 visitors, including 500 Russian nationals, were registered using the biometric control system during the first nine hours of 2018.
This system is in operation in Kyiv's international airports and at checkpoints on the Ukrainian Russian border as of 1 January.
