Context: Japan has introduced new yen banknotes equipped with 3D hologram technology to combat counterfeiting.
- The existing currency remains valid, with new bills gradually entering circulation through banks and ATMs to accommodate Japan’s cash-centric transactions.
What is 3D hologram technology?
It creates three-dimensional images that appear to have depth and motion without the need for special glasses. It uses principles of interference and diffraction. It uses lasers to record light patterns reflected from an object, producing a realistic holographic image that changes perspective as the viewer moves. These holograms are used for security in currency, authentication of products, and immersive displays in entertainment and education.
