Simplification
Before the installation of automated pre-security entrance control from Objective airport staff scanned the boarding passes manually. At its simplest, Objective's software reads the passenger's document to ensure it is a valid boarding pass, the basic test for whether they are allowed to pass through a security point. This alone takes much of the effort away from the agents at the control points, leaving them free to deal with any other processes they may be responsible for, such as image capturing and security profiling.
During peak hours, when the passenger flow reaches its maximum, serving every single passenger can become an issue. This is when Objective's pre-security software reaches its highest efficiency. Billund Airport has several gates for the passengers to use, and these can be combined to ensure that the passenger service rate is always at its highest level. Since the airport doesn't have the bottleneck anymore, the passenger saves time which can be used in the departure hall, in the shops and in the cafes increasing the airport profit.
