Why don't we use holograms for ID cards to prevent easy duplication?

Holograms are indeed a advanced security feature that can make ID cards more difficult to counterfeit. Several countries and organizations already use holograms on ID cards, passports, and other secure documents to prevent duplication. The reasons why holograms are not universally used on ID cards include: 1. Cost: Adding holograms to ID cards can increase production costs. 2. Technology: Creating high-quality holograms requires specialized equipment and expertise. 3. Standardization: There is no global standard for hologram technology, making it challenging to ensure compatibility and authenticity across different regions. 4. Security features: ID cards often incorporate multiple security features, such as biometrics, magnetic stripes, and smart chips, which provide robust security without relying solely on holograms. 5. Practicality: Holograms can be sensitive to light, temperature, and wear, which may affect their appearance and authenticity over time. Despite these factors, holograms remain a valuable security feature, and their use is expected to grow in the future, especially with advancements in technology and standardization.
