A modern system for self-scanning of boarding passes at the first check-in is about to be introduced at Sofia Airport. The system has already been ordered and is expected to be delivered next month, TravelNews reports. Thus, already on level 0 of Terminal 2 of Sofia Airport, all passengers will scan the bar code on their boarding passes themselves. With a correct boarding card, the doors will open automatically and people will go to the next level for the scanner check, explains Dimitar Bykov, Director of Business Development at SOF Connect, the airport's concessionaire.
