All prepaid bus cards issued by other cities in Taiwan will be able to be used in Taichung City as early as mid-2011, the Taichung City government said Monday. The central Taiwan's city's public transportation system at present only accepts Taiwan Easy Go prepaid bus cards, which can also be used in central Taiwan's Changhua and Nantou. Wen Tai-hsin, director of the Department of Transportation of Taichung City government, said that if everything goes smoothly, all prepaid transportation cards operated in other cities -- including Taipei's EasyCard -- will be able to be used in the central Taiwan region. The total cost for launching the integrated system is estimated at NT$100 million, he added. More than 1,500 card reader systems on buses in Taichung, Changhua and Nantou will need to be reconfigured, and the city has applied for a subsidy of NT$45 million from the Ministry of Transportation and Communications to integrate the system, Wen said.
