Abstract
A system for entrance permit control is configured to monitor individuals in an entrance region that includes an entrance to a restricted area. The system performs a monitoring method to enable a seamless entrance experience for the individuals. The system receives a stream of digital images of the entrance region, and processes the received stream of digital images for detection of a machine-readable code, MRC, displayable on an entrance permit carried by an individual in the entrance region. The system further tracks, based on the received stream of digital images, a location of the MRC within the entrance region, initiates a validation of the MRC, and provides, in dependence of the validation and position data generated by the tracking, a visual indication of a result of the validation on at least one of the entrance permit and the individual.
