The story
JETCO was founded by the Hong Kong Branch of the Bank of China (now Bank of China (Hong Kong)) in 1982 along with the Bank of East Asia, Chekiang First Bank, Shanghai Commercial Bank and Wing Lung Bank, and at present covers all banks in Hong Kong and Macau, except for HSBC and Hang Seng Bank, which uses a separate system known as ETC (易通財).
