OEM
Abbreviation for "Original Equipment Manufacturer". OEM modules from G&D are the LBCI, Lobby^® 90, and BIM 20x0. These are installed in the host machines by the integrators/machine manufacturers.


OEM module
Original Equipment Manufacturer modules that are integrated into a complete system, such as cash insertion mechanisms in ticket machines or in bank deposit machines.


OLE (object linking and embedding)
A method for sharing information. The data from a source document are linked or embedded in a target document. If the embedded data in the target document are highlighted, the source application opens so that the data can be edited in the native environment with the necessary functions.


On-card matching
G&D supplies a fingerprint application with on-card matching technology. On-card matching is the comparison of specific features against reference features within the card. The Giesecke & Devrient design is therefore set up for the exclusive storage of the reference data in the secure smart card environment - “personal data on the personal card”.


One-way function
Mathematical function for which there is not inverse function or which is extremely difficult to invert.


Online banknote packing system
The banknote processing system transports, labels, packs, and sends the banknote bundles are to the tray online and without any manual access.


Open application
Application on a smart card that is available to different service providers (such as retail trade, service providers) without requiring a legal connection.


Open OS
Open operating system; An operating system that is not owned by an individual card manufacturer such as Javacard, intelligent cards for Windows or Multos.


Open purse
Realization of an open application for an electronic purse. This can be used for general payments at various service providers.

Operating system
Even smart card microcontrollers require an operating system. There is not user interface – other than in a PC. The secure administration of data and controlled access has priority. With the help of cryptographic functions, this access protection is ensured by the operating system using preset command structures. It separates the various applications, denies unauthorized access, and controls the data transmission to the terminal and/or other cards. The G&D STARCOS^® operating system permits the use of various applications and functions such as electronic purses, loyalty applications, or the digital signature.


Operator
The person who feeds the deposits into the currency processor and operates the system.

Optical memory cards
Optical memory cards with several megabytes of storage can be used for applications where the smart card memory capacity is not sufficient. However, optical storage media can only be written to once and cannot be erased at will. Interesting aspects result from the combination of optical storage and chip technology: This lets large amounts of data be encrypted and written to the optical memory. The key, on the other hand, is kept securely in the protected chip memory; this also allows for the storage of large files such as images on cards.


Orientation
There are four different orientations (stacking possibilities) for a banknote: Faced (front), faced upside-down, unfaced (back), unfaced upside-down.


Orientation sorting
Sorting in all four orientations. Every banknote is stacked in a pre-determined delivery stacker according to its orientation. This results in a banknote bundle in which all banknotes are faced the same, even if mixed orientation banknotes were inserted in the singler.


Origination
Holographic recording procedure with the help of laser or electron beams; there are different origination techniques such as the classic direct lighting, ebeam, dot matrix, or holomax.


OTA
Over the air, a transmission over microwave channels. This acronym is used in the world of wireless telecommunication.


OVD element (also OVID, DOVID)
“Optically variable devices” are images and/or colors that change when viewed from different angles. Sometimes the terms OVID (optically variable image device) and DOVID (diffractive optically variable image device) are used.


OVS
Optically variable stripe; hologram stripe applied on banknote and securities paper; Louisenthal first used this in 1994 on the Bulgarian 2000 lewa banknote. See also LEAD – combination of hologram foil and intaglio printing.
