What is a "hologram" used for in banking?

A hologram in banking serves primarily as an anti-counterfeiting measure on bank cards. The use of holograms provides a unique visual element that is difficult to replicate, thereby enhancing the security of the card. This feature acts as a deterrent to fraud and counterfeiting, making it challenging for criminals to produce fake cards that can evade detection.

While the other options touch on aspects related to banking technology and security, they do not accurately reflect the specific purpose of holograms. Enhancing the digital experience, serving as a form of digital identification, and transaction verification involve different technologies and methods that do not utilize holograms in the same way. Holograms are specifically integrated to protect card information and establish authenticity, which is crucial for maintaining trust in financial transactions.
