The high-end scanning system from Eventgoose, we are very proud of. For smaller events with lower visitor numbers (up to 400 per hour), the Eventgoose App is perfectly capable of doing the access control yourself, with a smartphone/tablet.
For events with a higher number of visitors, scanning is done with the Eventgoose scanning software, which can be downloaded onto a pc/laptop. Multiple devices can then be connected (wirelessly) so that large groups of people can be scanned inside. The scan software is developed in such a way that there is a minimal response time, making long queues a thing of the past.
