Optical Security Foils

---

Optical security foils remain a core protection element across high‑value documents and product authentication.  Across hundreds of banknote denominations, as well as financial transaction cards, driving licences, and passports, optically variable devices (OVDs) continue to be one of the most trusted authentication features. ICAO even recommends a DOVID to secure passport biodata pages. Brands also rely on secure optical foils to help consumers and authorities verify genuine products and combat counterfeiting.
