Holographic Versatile Card. The Holographic Versatile Card (HVC) was a proposed data storage format by Optware; the projected date for a Japanese launch had been the first half of 2007, pending finalization of the specification, however as of January 2025, nothing has yet surfaced.This issue may be related to the bankrupt of certain entities once responsible for the development and ...
An "informative" (i.e. non-mandatory) annex [7] describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around the perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 ...
Plastic credit cards. Plastic cards usually serve as identity documents, thus providing authentication.In combination with other assets that complement the data stored on the card, like PIN numbers, they also serve authorization purposes, most often as bank cards for allowing their holders to do financial transactions.
Holographic data storage is a potential technology in the area of high-capacity data storage. While magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium, holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same ...
[citation needed] The term "hologram" has taken on a secondary meaning due to the widespread use of a multi-layer image on credit cards and driver licenses. This type of "hologram" consists of two or more images stacked in such a way that each is alternately visible depending upon the angle of perspective of the viewer.
Digital holography is the acquisition and processing of holograms with a digital sensor array, [1] [2] typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers ...

Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms.It involves generating holographic interference patterns.A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography.
