Bedford, Mass., October 6, 2003 – Reveal Imaging Technologies, Inc., a developer of operationally compatible security inspection systems, announced today that it has secured $10 million in Series A funding from IDG Ventures, General Catalyst Partners and Greylock. The company will use the financing to further develop and market its next-generation explosives detection systems (EDS) for airport checked baggage inspection, government and private facility protection and inspection of airfreight

In response to new legislation created after September 11th, US Airports are required to inspect 100% of checked passenger baggage for explosives. To date, most US airports inspect bags using large EDS systems and explosive trace detectors (ETD) in airport lobbies. Integrating the inspection process to improve the passenger flow and to significantly reduce the TSA labor costs requires airports to expand terminals and reconstruct baggage conveyor systems. Construction alone can cost tens, even hundreds of millions of dollars per airport. Industry analysts estimate that it will cost $5 billion to integrate checked baggage inspection at US airports.

" Rather than change the airport to accommodate the screening systems, we designed a screening system that fits the way an airport operates," said Michael Ellenbogen, president, Reveal Imaging Technologies. "Reveal is developing a unique new EDS that is less than half the size of current EDS machines and can be integrated directly into the airport check-in desk. Eliminating the need to reconstruct the baggage conveyor system enables airports to achieve 100% in-line screening at a fraction of the cost of today’s in-line EDS option."

The check-in desk is an ideal location and opportunity to inspect baggage, while the ticket agent issues the passenger boarding pass. Reveal’s system can be integrated quickly and easily into the check-in desk giving airports the benefit of integrated screening without the infrastructure costs associated with a major airport construction program.

"Reveal’s innovative technology, coupled with the extended opportunity that screening during the check-in process allows, enables the highest levels of detection performance while decreasing the false alarm rate." Said Dr. Richard Bijjani, chief technology officer, Reveal Imaging Technologies.

"The Reveal team has a proven track record in the security industry and extensive experience building solutions that are operationally compatible with airports and airlines," said Chip Hazard, managing general partner, IDG Ventures. "Reveal’s InLine Check In Station is the first new alternative for in line screening since the change in US aviation security regulations."
