The new Hong Kong banknotes to be issued in the final quarter use the latest printing technology to incorporate advanced secutiry features to make life difficult for counterfeiters to imitate or replicate them.

The security features are placed uniformly across all five denominations.

The six key features are:

Dynamic shimmering pattern - when the note is tilted, the shimmering ring in the pattern moves correspondingly.

Windowed metallic thread - when the note is tilted, the large and small rings on the metallic thread move correspondingly.

Improved watermark - the theme of the bauhinia flower is used such that the flower, leaves, bud and denomination numeral can be seen when the note is held up to the light.

Fluorescent see-through denomination - the patterns on the front and back, which are of a single color under normal light, will appear as two fluorescent colors when exposed to ultraviolet light. The patterns on the front and back fit to form the denomination numeral when the note is held up to the light.

Concealed denomination - when the note is tilted under the light, the denomination numeral hidden in the background can be seen.

Embossed feel - raised printing gives the note a strong embossed feel by touch.

Some people say they feel a little unnerved by Bank of China's version of the $100 note, which features a female Cantonese opera performer, because of its likeness to paper money (link in Chinese) meant for use in the afterlife."The design is very scary. One should spend it right after receiving it. I don't dare to bring it home," wrote one on Facebook. "The design looks like a cooperation with the ghost bank," said someone else on the social-media site.
