- 11. Watermark Magnetics™ is a form of magnetic stripe technology that uses a unique manufacturing process to incorporate an indelible “Watermark” number into the data stripe. 11
- 12. Proximity Cards: Technology uses a tuned RF circuit to emit a unique identification over relatively short ranges. The card requires no contact with the reader for the data to be read 12
- 13. Benefits: •Uses passive cards (no battery) for long lifetime •Non-contact readability for convenient & easy use. •Small unobtrusive readers. •Maintenance frees. •Cards can be supplied in credit card size with integral magnetic stripe for multi-function applications. Applications: •Medium/High security. •Where convenience of use is a high priority. •Where multi-function cards are desirable. 13

- 17. PROXIMITY CARDS ARE… *** SECURE, ***STYLISH, ***STRAIGHT FORWARD 17
- 18. Digital Keypads In this case, the "token" is simply a numeric code entered into a keypad on or near the door. Codes can usually be set to different lengths and most keypads have the capacity for more than one code. 18
- 19. Cryptag RF-ID Cards Cryptag RF-ID card technology uses radio frequency (RF) circuits encoded with unique data which are embedded into a plastic card which can transmit identification data to a card reader when within the reader’s RF range. The card does not require insertion into or physical contact with a reader in order for data to be obtained. 19
- 20. Benefits: • Almost impossible to duplicate cards due to RF circuitry and microchips embedded. • Non-contact readability provides easy use. • “On-the-fly” identification is available where the proximity card is interrogated without the cardholder having to stop or “show” the card to a reader. • Low maintenance reader due to non-contact of cards. • Slot-less reader and concealed installation makes vandalism less likely. 20
- 21. Benefits: •Equipment such as portable computers can be “tagged” as a deterrent to theft. •Variety of reader ranges and area coverage available. •Encrypted communications eliminates interference with other electronic and RF based systems. •Passive tags available that do not require batteries thus reducing on-going costs. Applications: • High security hands-free applications. • Ideal for non-interventional tracking of people, vehicles and assets. Especially suitable for disabled, elderly and 21
- 22. Wiegand Cards Wiegand Technology uses short lengths of special alloy wire with unique magnetic properties embedded into the card. The number of wire lengths and their location within the data strip determine the identification of the card. Applications: High Security. 22
- 23. Benefits: • Data strips are embedded within the card and cannot be seen on the card surface. • Almost impossible to duplicate cards as attempts to expose the embedded codes will move their precise location thereby making the card unusable. • Readers can be used indoors and outdoors. Specials finish readers available. 23
- 24. What is Biometrics? •Based on scientific fact that few body parts of every human being have distinct features unique and different than others. •Finger prints, shapes of iris, retina, body odor etc. are few such attributes which are used for identification purpose. •Biometric characteristic or a biometric trait, is a measurable physiological or behavioral trait of a living person that can be used to determine or verify the identity 24
- 25. What is Biometrics? •Physiological biometrics (also known as static biometrics): Biometrics based on data derived from the measurement of a part of a person's anatomy. Examples include fingerprints and iris patterns, as well as facial features, hand geometry and retinal blood vessel patterns. •Behavioral biometrics (dynamic biometrics): based on data derived from measurements of an action performed by a person and, distinctively, incorporating time as a metric — i.e., the measured action has a beginning, middle and end. Examples include voice (speaker verification) and signature. 25
- 26. Types of Biometrics • Fingerprint Biometrics • Hand Geometry Biometrics • Retina Recognition • Face Recognition • Palm / vain pattern • Voice Recognition Finger Print Biometrics 26
- 27. How it works? There is an optical device that uses digital holography to 3-D scan a finger and compare it against a previously enrolled template. Templates are stored as an ASCII file against as ID number. This system comprises of a reader, a processor and a power supply. To enroll a person takes 25 seconds approximately. A person carries out verification by entering PIN (personal identification number) or swiping their card and placing their finger on the reader platen. 27
- 28. Standalone Fingerprint Module •Verification means that the system is used to verify the identity of the person seeking access. This is the most secure access control mode available. •Identification means that the system is being used to identify the person without requiring provision of any other source of identification - except himself. •Identification System can be configured to be non-invasive and user-friendly. 28
- 29. What are the benefits? • For Users: •Convenience - (in Identification mode) no card key to keep track of or access code to remember • For Administrators: •Peace of mind - secured areas are protected from inadvertent lapses in security and from knowledge that you are no longer reliant on token-based security alone. 29
- 30. What are the benefits? •Affordability- in many cases, enhance security without replacing existing security devices. • Compliance – If you simply don’t want someone being where they shouldn’t be, system can be configured to actively look for individuals, identify them, & notify administrator if person approaches secured area. 30
- 31. Benefits: •Fully featured biometrics fingerprint reader. •Multiple finger enrolment. •Very low false acceptance rate of less than 0.0001 •Fast verification. •Requires a 3 dimensional finger - thus copies or images provide no risk or threat to security. Applications: • Very high security • Access control to buildings, car parks, isolated and remote facilities. • ATM, vault and safe control. • Identity verification of visitors to secure installations. • Prisons and military establishments. 31
