Driver less Train:
China has made large investments in transport systems throughout Beijing to ease the way for the 3 million spectators who will pour into the city for the Olympics. Two subway lines and a driverless rail system, which runs both above and below ground comes to the rescue.
The 28-km rail link between Beijing Capital International

This driverless trains run 62.5 miles per hour making the entire journey from the Beijing airport to the center of the city only 16 minutes. They can carry 4,500 passengers an hour.
RFID Olympics Tickets:
Radio frequency identification technology is taking care of ticketing for the estimated 3 million athletes, journalists, and spectators. These 13.56-MHz HF RFID chips is linked to a remote database, designed primarily to combat counterfeits, facilitate check-in, and so on. Chinese local authorities will also be using an RFID-based food management system to maintain close tabs on food production, processing, and deliveries.
LEDs used at venues:
CREE Inc. is providing about 440,000 LEDs to illuminate the exterior of the Water Cube, where water-sport events will be held. Contractors for the Beijing Olympics found LEDs a more colorful and lower power route to lighting up their creations.
