Banknote security 上市 Deposited
- Modern banknotes use several anti-counterfeiting devices. Optical variable devices (OVD) can be added to banknotes with heat transfers and holograms on modern currency. Some high-value bills have up to 50 security elements. These include multiple alphabetical fonts, watermarks, security threads, different sizes and shapes for letters and digits in serial numbers, and inks only seen under ultra-violet or infrared light. The best of banknotes have micro-printed surfaces.
