Public recycling bins that use RFID to credit recyclers every time they toss in a bottle; pressure-sensitive floors in the homes of older people that can detect a fall and contact help; phones that store health records and can be used to pay for prescriptions.
In New Songdo City, a "ubiquitous city" being built in South Korea, all major information systems (residential, medical, business, governmental, etc.) share data, and computers are to be built into the houses, streets and office buildings.
When completed in 2014, the city's infrastructure will be a test bed for new technologies, and the city itself will exemplify a digital way of life, the "U-life." It starts with a resident's smart-card house key. "The same key can be used to get on the subway, pay a parking meter, see a movie, borrow a free public bicycle and so on. It'll be anonymous, won't be linked to your identity, and if lost you can quickly cancel the card and reset your door locks," aid John Kim who leads the U-city planning.
