What function does a Hologram serve on bank cards?

The function of a hologram on bank cards is primarily focused on its role in anti-counterfeiting. Holograms create a three-dimensional image that is difficult to replicate accurately, thereby serving as a security feature to confirm the authenticity of the card. The unique light-reflecting properties of holograms allow them to display images that can change appearance based on the angle of the viewer, making it harder for counterfeiters to forge genuine bank cards. This advanced technology acts as a deterrent against fraud, as the presence of a hologram signals to users and merchants that the card has been issued by an authorized financial institution.

While some may see the hologram as merely a decorative feature or a way to enhance the visual appeal of the card, its primary purpose is to establish trust and security in payment transactions.
