Reserve Bank of Australia is now introducing a new $5 banknote design that's packed with security features to make it one of the world's most difficult notes to counterfeit.
At its surface level, the banknote design boasts a colorful look that changes hues from pink and purple to orange. In the middle of these gradients is a top-to-bottom clear panel that is actually a security feature in itself.
The $5 note also features a number of elements that change dynamically as the banknote is moved. This includes an image of a bird native to Australia that appears to flap its wings when moved, a number "5" that reverses and a patch that has a "rolling" color effect. On top of this, there's also a small tactile area that will be of use to individuals with vision impairments.
