Scanning the QR code creates a new visit for the user and permits the activation of the GPS positioning needed to track the user through the building for a limited time. The access time is determined by the owners to limit the usage of the building plans for visitors making use of the facility. The QR code gives the user access to the basic layout of the building which is provided by the building owners. The plans are only required to show interior and exterior walls, entrances, exits and movement routes to provide a level of security for the building. Sensitive information is excluded to add privacy and does not allow the public free access to complete building plans.

Through the scanning of the QR code, an immediate navigational course can be plotted to direct the user from their current position inside the building to the nearest emergency exit. The navigational system process is explained in Figure 18 below:

Figure 17 gives a graphical representation of the live tracking system that is activated with each new visit created by a user. This tracks the users location in the background while they carry on with business as usual.
