Vetting Indicator Kits are comprised of a specified number of vetting indicators and one slider. See individual kits for specific details.
The vetting indicators are customized for each airport with their code and a numbering system. Each indicator type will be unique externally and internally (officers will be able to easily identify indicators when placing them on the belt and when viewing them on the x-ray machine).
The sliders are adhesive to the x-ray and have two distinctive sides to indicate the passenger status (Pre✓ or Standard).
