  2. Holographic Versatile Card - Wikipedia

    en.wikipedia.org/wiki/Holographic_Versatile_Card

    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 ...

    en.wikipedia.org/wiki/Holographic_data_storage

    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 ...

    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.

  6. Eurocard (printed circuit board) - Wikipedia

    en.wikipedia.org/wiki/Eurocard_(printed_circuit...

    Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.

  7. Computer-generated holography - Wikipedia

    en.wikipedia.org/wiki/Computer-generated_holography

    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.

  8. Security hologram - Wikipedia

    en.wikipedia.org/wiki/Security_hologram

    [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.

    X (requires an eXternal adapter) – Technically the same as E, but such adapter usually consists of 2 parts: a pseudo-card with pin routing and physical enclosure size that perfectly match the target slot and a break-out box (a card reader) that holds a real card. Such adapter is the least comfortable to use.
