Holographic seals are advanced security features that use holography to create three-dimensional images. These seals are often used on products, documents, and packaging to prevent counterfeiting and ensure authenticity. When viewed from different angles, the holographic image changes, making it difficult to replicate. These seals can incorporate various elements, such as barcodes or QR codes, which can be scanned for additional verification. Holographic seals are commonly found on items like credit cards, passports, and brand packaging, providing a visual assurance of legitimacy and enhancing security measures against fraud.
