The automatic border control system was introduced to help ease congestion during peak hours.
Kuopio-based musician Seppo Parkkinen travels internationally a dozen times a year.
"It [automatic passport control] is much faster, you don’t have to wait and it works really well."
Citizens of the European Economic Area, Switzerland and Japan holding biometric passports can pass through the self-service passport control. Users scan their passport in a reader and later pose for a camera that uses facial recognition technology. It compares their features with a digital photo embedded in the passport.
Last year 600,000 passengers walked through the automated gates, and a million are expected to do so this year.
Pentti Alapelto of the Finnish Border Guard says 70 percent of Finns have a biometric passport. By the end of 2016, that figure will be 100 percent.
The high-tech readers also offer an additional layer of security to traditional passport control.
"We also use the devices to help weed out passengers in cases where we believe a someone is travelling with a false document," explained Alapelto.
