Airports have taken advantage of digital signage technology for years, but only indoors. Now the CyRAQ 1000 series of sunlight-readable outdoor digital signs expands the profit potential to train and subway stations, bus shelters, street furniture, docks, and the outdoor areas of cruise ships. Keep passengers informed of schedules and routes, and take the sting out of delays by posting them promptly. Promote excursions and attractions. Add a new revenue stream with third-party advertising. And if you can document when the ad appeared and how many people saw it, advertisers will pay a premium.
