High-Contrast Colors and Sharp Movement


High Definition Security

Movements with Extreme High Contrast

RAPID® HD is an advanced form RAPID micro-optic security, first introduced by Crane Currency in 2014. RAPID HD provides high engagement and ease of use. It affords new customizable design possibilities with a broad palette of rich colors that highlight sharp, fast movement effects.

In the domain of public security, contrast and movement are critical to providing easy and intuitive authentication. Easy to see movement is the public’s most important visual cue for verifying authenticity quickly and decisively. RAPID HD security threads exhibit high contrast movement effects with images and colors that can exactly meet the theme of the banknote. The security thread exhibits distinct, easy to verify movement. Always with only a ‘flick of the wrist’ and in any lighting condition.

RAPID security thread has claimed the industry’s distinction of having the fastest and easiest-to-verify movement. RAPID HD raises this already high bar through advancements in material properties and processing that yield results that are deservedly described as high definition or “HD”.


More Secure, Less Material

RAPID HD packs increased security and ease of use into a security thread that is nearly 10% thinner than traditional RAPID. This means its integration is made even easier.


Durability & Post-Print Varnishing

RAPID HD security thread is highly durable. It is resistant to soiling and oils and can be post-print varnished.

Machine Verification


RAPID HD Detect uses a secure IR material that is invisible to the public and can be detected by nearly all manner of cash processing equipment. Only available to the currency industry, Detect exhibits a unique highly secure IR signal.


RAPID security thread is one of the most secure and popular banknote security features and has been used to protect over 100 denominations of banknotes.
