Abstract
A method and apparatus that validates a hologram by scanning the hologram at multiple angles is disclosed. The method may include scanning a document containing the hologram at a first angle to create a first image, scanning the document containing the hologram at a second angle to create a second image, determining whether the hologram is valid, and sending the validity determination to a user interface for display to a user.
