Tips on spotting a fake
Police provided tips on how the public can recognise counterfeit notes.
* Holographic window thread: on genuine notes, it has clear text and good-quality holographic images showing 'HK1000' and the bauhinia flower pattern, but on counterfeit notes it does not shimmer as much and the text is unclear.
* Silver metallic ink on front circular pattern: on genuine notes, it is bright and shiny, but dull on counterfeit bills.
* Concealed denomination in lower right side: when viewed horizontally, the numbers '1000' can be seen on genuine notes, but the image is weak or missing on the fakes.
* Police also set up a hotline - 2860 5012 - for the public to report any suspicious banknotes.
