This Hong Kong 20 Dollar banknote from 2010 was designed to showcase the beautiful natural scenery of Hong Kong. Its front design depicts the Bank of China Tower, the bank logo, and numeric 20 and bauhinia flower in SPARK with the denomination as a registration device. The reverse side features a picturesque view of the buildings along the shore of Repulse Bay. The note is 143 x 71.5 mm in size and contains a green-to-magenta windowed security thread with demetalized HK20 and a large HK made up of small letters to enhance its security features. Placing the note under a UV light would reflect a watermark image of a Bauhinia flower and electrotype 20 on pixelized design.
