Low Coercivity view

Also known as: lo-co, lo co, low-coercivity, low coercivity, loco

Magstripes come in two main varieties: high-coercivity (Hi-Co) at 4000 Oersted and low-coercivity (Lo-Co) at 300 Oersted but it is not infrequent to have intermediate values at 2750 Oe.In practical terms, usually low coercivity magnetic stripes are a light brown color. Low coercivity stripes are easily damaged by even a brief contact with a magnetic purse strap or fastener. Because of this, virtually all bank cards today are encoded on high coercivity stripes despite a slightly higher per-unit cost. Magnetic stripe cards are used in very high volumes in the mass transit sector, replacing paper based tickets with either a directly applied magnetic slurry or hot foil stripe. Slurry applied stripes are generally less expensive to produce and are less resilient but are suitable for cards meant to be disposed after a few uses.

Oersted view

Also known as: Oersted

The unit of magnetizing force (magnetic field strength) in the CGS electromagnetic system.

CR80 view

Also known as: CR80

CR80 format specifies a card size of 85.60 × 53.98 mm (3.370 × 2.125 in),  thickness of 0.76 mm and corners rounded with a radius of 3.18 mm. Commonly used for bank cards, ID cards, loyalty cards and membership cards.

High Coesivity view

Also known as: Hi-Co, hico

Magstripes come in two main varieties: high-coercivity (Hi-Co) at 4000 Oersted and low-coercivity (Lo-Co) at 300 Oersted but it is not infrequent to have intermediate values at 2750 Oe. In practical terms high coercivity stripes are nearly black. High coercivity stripes are resistant to damage from most magnets likely to be owned by consumers, virtually all bank cards today are encoded on high coercivity stripes despite a slightly higher per-unit cost.

Magnetic Stripe view

Also known as: magnetic stripe, mag stripe, mag strip, magnetic strip, magnetic stripes, Magnetic stripe, Magnetic Stripe

A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called a magstripe, is read by physical contact and swiping past a reading head. Magnetic stripe cards are commonly used in credit cards, ID cards, transportation tickets, and so on.

Proximity view

Also known as: prox, proximity

Proximity card is a generic name for contactless integrated circuit devices used for security access or payment systems. It can refer to the older 125 kHz devices or the newer 13.56 MHz contactless RFID cards, most commonly known as contactless smartcards.

Also known as: mifare

MIFARE is reputedly the most widely installed contactless smartcard technology in the world with 500 million smart card chips and 5 million reader modules sold. The technology is patented by NXP Semiconductors. The MIFARE propietary technology is based upon the ISO 14443 (RFID) Type A 13.56 MHz contactless smart card standard.

YMCKO view

Also known as: YMCKO, CMYKO

Five panel full colour plastic card printer ribbon. Utilises a yellow, cyan, magenta, black and overlay ribbon panel to produce all colours except metallic silver and gold. Most commonly used for ID badges or membership cards.

Lanyard view

Also known as: lanyard

Simple lanyards are made of braided fabric with a clip attached to the end. They are often used in business situations where lanyards can be personlaised with brands or other designs to promote events, products or services. Lanyards can be used for holding name badges; the typical arrangement is to attach a plastic pouch with at least one clear side to the lanyard, with the person's name badge facing the front. Lanyards are also widely used with small electronic devices. With increasing miniaturisation, many cameras (both digital and film), MP3 players, and USB flash drives include lanyards, providing easy portability and insurance against loss or dropping. Electronics designed to take a lanyard usually have a small through-hole built into a corner or edge of the case, or anchored to the frame of the device; the corresponding lanyard generally has a loop of thread on the end that is attached to that hole with a simple knot, usually a cow hitch.

Dye-Sublimation view

Also known as: Dye-Sublimation, dye-sub, dye sublimation

A dye-sublimation printer (or dye-sub printer) is a printer which employs a printing process that uses heat to transfer dye to a medium such as a plastic card, printer paper or poster paper. The process is usually to lay one color at a time using a ribbon that has color panels. The overcoat panel (which has numerous names depending on the manufacturer) is effectively a thin laminate which protects the print from discoloration from UV light and the air while also rendering the print water-resistant. Sublimation is when a substance transitions between the solid and gas states without going through a liquid stage; dry ice is an example. In a dye-sublimation printer the printing dye is heated up until it turns into a gas, at which point it diffuses onto the printing media and solidifies. Prior to printing, the dye is stored on a cellophane ribbon.

ID Card view

Also known as: i.d. id

An identity document (also known as I.D. or ID) is a piece of documentation designed to verify aspects of a person's identity. If an identity document is in the form of a small standard-sized card, such as an ISO 7810 card, it is called an identity card or ID Card.

Loyalty Card view

Also known as: Loyalty Card

In marketing and in retailing more specifically, a loyalty card, rewards card, points card, or club card is a plastic or paper card, visually similar to a credit card or debit card, that identifies the card holder as a member in a loyalty program. Loyalty cards are a system of the loyalty business model. In the United Kingdom it is typically called a loyalty card, in Canada a rewards card or a points card, and in the United States either a discount card, a club card or a rewards card. Cards typically have a barcode or magstripe that can be easily scanned, some modern systems now utilise chip card & RFID card technology to interact with central systems. Small keyring cards are often used for convenience.

PVC view

Also known as: PVC

Polyvinyl chloride, (IUPAC Polychloroethene) commonly abbreviated PVC, is a widely used thermoplastic polymer. In terms of revenue generated, it is one of the most valuable products of the chemical industry. There are many uses for PVC. As a hard plastic, it is used as vinyl siding, magnetic stripe cards, window profiles, gramophone records (which is the source of the name for vinyl records), pipe, plumbing and conduit fixtures.

Zebra Technologies view

Also known as: Zebra, Eltron

Zebra Technologies is a manufacturer of thermal bar code label and receipt printers, RFID smart label printer/encoders, and card printers, based in Vernon Hills, Illinois. Zebra has products in 100 countries around the world. Zebra-brand printers are used by more than 90 percent of Fortune 500 companies. Zebra plastic card printers were previously known as Eltron Card Printers.

Card Printer view

Card printers, often also called plastic-card printers, are electronic desktop printers with single card feeders which print and personalize plastic cards. In this respect they differ from, for example, label printers which have a continuous supply feed. Card dimensions are usually 85.60 × 53.98 mm, standardized under ISO 7816 as ID-1. This format is also used in EC-cards, telephone cards, EU drivers’ licenses and health insurance cards. This is commonly known as the bank card format. Card printers are controlled by corresponding printer drivers or by means of a specific programming language. The principle is the same for practically all card printers: the plastic card is passed through a thermal print head at the same time as a color ribbon. The color from the ribbon is transferred onto the card through the heat given out from the print head. The standard performance for card printing is 300 dpi (300 dots per inch, equivalent to 11.8 dots per mm). There are different printing processes, which vary in their detail. Alongside the basic function of printing cards, card printers can also read and encode magnetic strips as well as contact and contact free RFID chip cards. Thus card printers enable the encoding of plastic cards both visually and logically. There is a difference between single and double sided card printers with an automatic flipping station. Plastic cards can also be laminated after printing. Plastic cards are laminated after printing to achieve a considerable increase in durability and a greater degree of counterfeit prevention.

Radio-frequency identification view

Also known as: Radio-frequency identification, Radio-Frequency Identification, Radio Frequency Identification, radio frequency identification, RFID, rfid

Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennas. Passive tags require no internal power source, whereas active tags require a power source.

HDP view

Also known as: HDP, High Definition Printing

HDP - High Definition Printing™ High Definition Printing™ uses dye-sublimation technology to print crisp, 300-dpi images on the underside of HDP® Film developed by Fargo. The film is then bonded to the card surface with heat and pressure. By sandwiching images between the HDP Film and the card, High Definition Printing makes these cards tamper-evident and highly resistant to wear and abrasion. If a counterfeiter tries to peel the film apart in an attempt to alter the card, the printed image essentially destroys itself. The flexible solution for hard-to-print technology cards
High Definition Printing is ideal for printing the most commonly used technology cards, including contact and contactless smart cards, and clamshell proximity cards. The electronics embedded inside these cards often makes the card surface uneven — a problem for conventional dye-sub printing. But in High Definition Printing, the HDP Film flexes over the bumps, giving the card a smooth, even appearance. Since no printhead comes in contact with the card itself, High Definition Printing can also print right up to the edge of exposed smart card contacts. Conventional dye-sub printers must leave clear space around contact pads to avoid print head damage. Extra security and durability
Fargo HDP Film can be ordered with standard and custom holographic images to give your ID cards an extra layer of security. (CR-80 sized cards only.) If your Fargo HDP printer includes an optional card lamination module, you can make your cards up to 25 times more durable than HDP Film alone with a PolyGuard overlaminate. Overlaminates are also available with standard or custom holographic images.

HoloKote view

Also known as: HoloKote, holokote, Holokote, holoKote

If the card is mainly going to be worn as a photo ID badge, or if a shorter lifetime is acceptable, then Ultra's patented HoloKote™ technology will provide adequate physical protection together with complete protection against forgery at zero cost in consumables. The capital cost is also zero if the built-in "Ultra Secure" logo (included in the Alto, Rio 2 and Tango 2 printers) can provide adequate security protection, although the use of a customised logo is highly recommended. With HoloKote the authentication device is a single encrypted electronic key which cannot be duplicated and which is easily accounted for and safeguarded by locking it in the office safe when not in use. HoloKote™ puts a daylight visible frosted security logo over the entire face of the card, which makes it ideal for cards which are carried or worn as badges.

True Colors view

Also known as: True Colors, true colors, True colors, true Colors

For consistent high-quality output from your Zebra card printer, use Zebra’s TrueColours® print ribbons. TrueColours ribbons deliver vibrant color photos and “true-to-life” flesh tones, as well as sharp monochrome bar codes and text. Prolong card life with Zebra’s patented overlay (“O panel”) in the ribbons, which protects your card against dye migration and abrasions. TrueColours ribbons are also designed to help extend the life your Zebra card printer with a unique silicone-based coating that minimizes printhead debris. Ribbons without this coating allow particulate buildup on the printhead, which may decrease the life of this critical printer part. Zebra TrueColours® Monochrome Resin Ribbons use “thermal transfer” printing technology, a process by which a heated printhead is used to transfer a digitized image from the ribbon to the surface of the card. Monochrome ribbons can be used on all Zebra card printers. They are available in a variety of colors including black, red, green, blue, gold, silver, white and scratch-off gray. Zebra TrueColours® Multi-panel Ribbons are developed with the newest technology in dyes available. Multi-panel ribbons use dye-sublimation, which means the color dye is vaporized into a gaseous state and then diffused onto the cards at the printhead station. Prevent unauthorized use of your card printer and supplies with print ribbons that have factory programmed customer security codes. The printer will authenticate the ribbon security code before printing, helping keep your ID issuance process secure.

Access Control view

Also known as: Access Control

Access Control System Operation
Sometimes the best way to understand a system is to walk through a typical use of the system. In access control this typically begins when the user presents the assigned credential to the appropriate reader. The reader conveys the credential’s information to the device that makes the access decision. In most electronic access control systems this is a highly reliable independent control panel. The control panel is aware of the current time and date and decides whether the holder of the presented credential is allowed access at this door at this time and date. Whether access is granted or denied, the transaction is recorded providing a history that can be consulted when questions arise about who was in the protected area.

Access Control System Components
An access control point can be a door, turnstile, parking gate, elevator, or other physical barrier where the granting of access can be electrically controlled. Typically the access point is a door and the access is controlled through either a magnetic lock or electric strike. Knowing the position of the door is an important element of the system and is typically accomplished with a magnetic switch concealed in the frame of the door. This sensor is used to detect a door forced open without authorization or being held open too long after authorization. Sometimes there are additional sensors that monitor the state of the lock, motion in the protected area, and other alarm sensors. The user’s primary interface with an access control system is the credential reader. A reader reflects the technology of the credential. The reader for a magnetic stripe, bar code, or Wiegand card is typically called a swipe reader and is in common use in retail stores and ATMs. Some swipe readers require the card to be swiped in a specific direction in order to get a good read, but the typical swipe reader for access control can read the credential when it is swiped in either direction. The reader for a proximity or contactless smart card is actually a radio transceiver. The broadcast field of the reader activates the card, which then begins radio-based transaction with the reader. The smart cards with the gold contacts visible on the front of the card are known as contact smart cards and require the gold contacts to physically touch contacts on the reader to accomplish the transaction. Biometric readers are unique to the technology being used but always require the users to present some part of their body, whether it is actually touching the reader for fingerprint or hand geometry or looking at a camera in the case of face recognition, iris and retinal scanning or speaking into a microphone in the case of voice recognition. Entry into a protected area always requires a device to validate the person requesting access. Exit from a protected area may or may not require validation. When it does, a second reader, almost always using the same technology as entry validation, is used for exit validation. Even when exit validation is desired, fire and emergency codes require a means of exiting an area without validation. For that purpose there are a range of “Request to Exit” devices commonly called REX devices. A REX device may be as simple as a pushbutton or as sophisticated as a heat and motion detector. In any case the REX button will unlock the door for at least as long as the REX device is activated. If exit validation is not required, REX activation is considered normal operation. If exit validation is required, activation of the REX device may trigger an alarm. Each of the above devices is connected to an access control panel. This panel should be designed to operate standalone, in the absence of any supervising computer. The control device must have backup power capable of sustaining the operation of the system during a primary power failure for as long as it typically takes to re-establish primary power or make arrangements for an alternate power source. The access control panel must also detect and generate an alarm any time the control enclosure is opened so that a monitoring guard is aware of any attempts at tampering with the system. Summary
Electronic access control systems today range from standalone single door controllers to complex networked systems integrated with closed circuit television systems, burglar alarm systems, and other building control systems. The selection of the proper credentials and readers, the system features needed, and the many choices available for installation and implementation can require complex planning and difficult decisions. There are books available to help you learn more about these choices or you can contact a professional dealer to help you define your needs and arrive at an appropriate solution. If you would like to begin the process of defining your needs, try taking our free risk analysis. Credential
A credential is something you have, something you know, some biological characteristic, or some combination of these. The typical credential today is something you have such as an access card, key fob, or other key. There are many card technologies including magnetic stripe, bar code, Wiegand, 125 kHz proximity, contact smart cards, and contactless smart cards. A credential based on something you know can be a Personal Identification Number (PIN), a combination, or a password. The use of biological characteristics as credentials is generally called biometrics. Typical biometric technologies include fingerprint, face recognition, iris recognition, retinal scan, voice, and hand geometry. All card technologies are generally used to convey an identification number that is comprised of three components: the card number, the facility or site code, and the issue number. The card number is a unique number that distinguishes the cardholder from all other cardholders. The facility code, also called the site code, is a number that was created, when memory was expensive, to allow the range of unique numbers to be smaller while eliminating duplicate numbers. The issue number is incremented each time the card is replaced due to a lost or missing card. The identification number in most card technologies is generally stored in one of two formats: Wiegand or ABA. The Wiegand format, named for the card technology where the format was first used is bit-oriented and ranges from 26 to 60 bits long. The ABA format, named for the American Banking Association, is digit oriented and is typically found on credit cards or other cards using magnetic stripe technology.

Lithography view

Also known as: Offset Printing

Lithography or Offset Printing
Most common process for plastic card printing based on the concept that oil and water are not compatible. The ink represents the oil and the alkaline fountain solution represents the water. These are the two main components which must interact during the printing process, allowing the ink to adhere to the image area of a printing plate while the fountain solution repels the ink from the non-image area.

Degaussing view
