Proximity cards continue to grow in popularity because of the convenience they offer in security, identification, and access control applications, especially door access where fast, hands-free operation is preferred. Also referred to as "prox cards", they communicate through an antenna similar to contactless smart cards except that they are read-only devices that generally have a greater range of operation. The range of operation for prox cards is typically from 2.5" to 20" depending on the reader. It is possible to read a small amount of information with prox cards such as an identification code that is usually verified by a remote computer; however, it is not possible to write information back to the card. Prox cards are available from several sources in both ISO thickness cards from .027" to .033" and "clamshell" cards from .060" to over .070" thick.
Besides proximity cards, the most typical form of smart cards are contact smart cards. Contact smart cards are the size of a conventional credit or debit card with a single embedded integrated circuit chip that contains just memory or memory plus a microprocessor. Memory-only chips are functionally similar to a small floppy disk. They are less expensive than microprocessor chips, but they also offer less security so they should not be used to store sensitive or valuable information. Chips that contain both memory and a microprocessor are also similar to a small floppy disk, except they contain an "intelligent" controller used to securely add, delete, change, and update information contained in memory. The more sophisticated microprocessor chips have state-of-the-art security features built in to protect the contents of memory from unauthorized access. Contact smart cards must be inserted into a card acceptor device where pins attached to the reader make "contact" with pads on the surface of the card to read and store information in the chip. This type of e-card is used in a wide variety of applications including network security, vending, meal plans, loyalty, electronic cash, government IDs, campus IDs, e-commerce, health cards, and many more.
Other types of smart cards include:
Embedded holograms are one of the most dependable security methodologies available because the depth of the hologram, be it diffraction foil or 2D/3D prevents it from duplication via desktop copying or imaging software. Embedded holograms should not be confused with surface holograms that can ruin print heads and scratch or wear when used. Embedded holograms are appropriate for any application in which forgery is an existing, or even potential problem. Current applications include businesses and institutions as wide spread as: corporations, schools/universities, consulates, hospitals, ski lodges, governmental agencies and membership clubs. This versatile card is 100% video grade, and besides the area for the hologram, the card's entire surface is yours to use via dye sublimation or thermo transfer.
This technology protects your business or organization through the use of cards that automatically self-expire by changing color within one day. These expiring dyes can be used with any dye-sublimation PVC card printer. It's ideal for contractors, temporary employees, sales meetings or any application where there is a need for temporary access, and no way to collect badges at the end of a session.
Swipe cards are designed to tie-in identification needs with time and attendance systems, access controls and tracking of employee movement and access throughout your facilities. Swipe cards can be used in conjunction with loyalty card or other data gathering methodologies to provide important marketing information that would not be otherwise obtainable.
Magnetic stripe refers to the black or brown magnetic stripe on the card. The stripe is made of magnetic particles in a resin base with the density of the resin particle material determining the coercivity of the stripe. The higher the coercivity, the harder it is to encode… and also erase, providing a high level of security for your organization. Magnetic stripes are often used in applications that tie into access control and time and attendance, such as school or corporate lunch programs, library cards and more.
Bar codes are a recognizable part of today's culture. They are the symbol codes that you see on most any product in a retail establishment, consisting of a group of printed, variously patterned bars and spaces and sometimes numerals that is designed to be scanned and read into computer memory as identification for the object it labels. These bar codes can contain any number of data and can be used in conjunction with visual ID on a card to provide a set of characteristics.
Wiegand Wire (BeFe)
Wiegand technology is a highly secure, low cost and durable technology that is widely recognized and field proven for over 18 years. It is based on a pulse-generating phenomenon called naturally, the Wiegand effect. A special alloy wire is processed in such a way as to create two distinct magnetic regions in the same homogeneous piece of wire, referred to as a shell and a core. These two magnetic regions react differently to any applied magnetic field. The shell requires a strong magnetic field to reverse its magnetic polarity, whereas the core will revert under weaker field conditions. When the shell and core change to different polarity orientations, the Wiegand pulse is generated, and is sensed by a pickup coil (which is located in the card reader). Due to the complexity of manufacturing the Wiegand wire, Wiegand cards are virtually impossible to duplicate and remain one of the most secure access control technologies.
IDI specializes in providing customized card solution for all customers. All ID cards can have enhanced security by incorporating anti-counterfeiting solutions such as polyguards, holograms, holomarks, and verimarks. All of these methods provide highly secure cost-effective solutions that make overall security that much more effective.
A card overlaminate available in 1 mil and .6 mil thickness that provides extraordinary card protection. This is especially suitable for harsh environment that demand security. Available as clear or with embedded holographic-type security measures.
A visually dynamic card that's easy to validate and virtually impossible to duplicate. Holomark cards contain your customized holographic logo, as well as text or graphics available in gold or silver. This technique provides major protection against photo ID counterfeiting.
Verimark is a quick and affordable solution to anti-counterfeiting. Using a hot stamp process, we can embed your organization's logo, text or graphics onto a silver metallic foil to produce an easy-to-verify, visual counterfeit deterrent. These come as blank cards with your two dimensional customer logo, text or graphics in gold or silver foil.
