Upgraded $20, $50 and $1,000 bills are going into circulation today
New banknotes in three denominations - $20, $50 and $1,000 - go into circulation today.
The bills will be available at all branches of the three note-issuing banks - Bank of China, Standard Chartered Bank and HSBC.
The three denominations complete a new series of notes, with the first two denominations of $100 and $500 having been in circulation since December. All existing banknotes will continue to be legal tender.
The $20 note comes in a standardised blue, the colour of the $50 bill has been changed from violet to green, while the $1,000 note remains yellowish-gold. The Hong Kong Monetary Authority and the three note-issuing banks earlier rejected concerns that people could be confused by the green colours of the new $50 notes and the old $10 bills, saying they were a different size and design.
The new notes contain both improved and standardised security features to keep ahead of counterfeiters, making them more difficult to forge.
They include a holographic thread, iridescent images of the bauhinia flower and a bar code visible under ultraviolet light.
The new features include a denomination numeral which changes colour between gold and green when viewed from different angles.
These additions bolster existing security measures, which include highlighted watermarks, a security thread and invisible fluorescent fibres.
Leaflets explaining and illustrating the notes' new security features are available from branches of the note-issuing banks and the Monetary Authority.
The information is also available on the authority's website at www.hkma.gov.hk , and the websites of the issuing banks at www.bochk.com , for the Bank of China, www. standardchartered.com.hk and www.hsbc.com.hk .
