To push electric cars, Seoul rolls out portable chargers with RFID

Seoul is trying to put one of the world's highest concentrations of electric vehicles (EVs) on its roads with a project that would let drivers charge their vehicles in residential parking lots and other everyday locations. The city is planning to give out electric charger cables fitted with RFID readers that would allow drivers to recharge their batteries through standard power outlets at 100,000 locations -- a huge increase from current numbers.
