Hologram

A hologram on a credit or debit card is a security feature that consists of a three-dimensional image embedded into the card's surface. This image is created using holographic technology, which captures light field data rather than merely reflecting a photographic image, allowing the picture to display depth and parallax when viewed from different angles.

The primary purpose of incorporating a hologram on cards is to enhance security by deterring counterfeiting and duplication. Holograms are difficult to replicate accurately without access to specialized equipment and technology, making fraudulent copies easier to detect. Common holographic images include bank logos, security symbols, or other intricate patterns that are visually distinctive.

Credit card companies and financial institutions use holograms as part of a multi-layered approach to card security, often combining them with other features like chips, magnetic stripes, and advanced encryption technologies. These combined security measures help protect consumers' financial information and reduce the incidence of card fraud.
