Access Control Technology

Keypads
Keypads are the most basic of access control entry equipment, whilst there simplicity can limit there functionality, they are easy to use and require very little maintenance.

Locks
Locks are the mechanical interface between interface software and hardware in access control systems. There are many types of locks, to suit situation and requirement. "Mag locks" for example, offer very high levels of security whilst being cost effective. Traditional strike locks can be integrated into electronic latches.

All locks need to have an electronic element to ensure that they can be released via any one of the various interfaces.

Swipe Cards
Swipe cards can be divided into three main sub-categories - Magnetic, infra red and Weigand. To the user they all operate in a similar manner, the card is swiped through a reader, but each category requires its own reader technology. The use of a card allows for extra information to be carried on it. For example a picture, text, bar coder, and depending on the card another data stripe, for example a magstripe can be added to an infrared card.

Proximity & Handsfree
Proximity readers offer a totally non contact solution. Unlike other types of readers proximity readers can be hidden behind walls or doors. These readers are very useful in places where vandalism is high or likely to occur. Proximity readers work in a similar way to the handsfree systems although allow for greater distances between the reader and the proximity device. It is possible to use proximity readers in conjuction with car park barriers.

Biometrics
Biometrics are automated methods of recognising a person based on a physiological or behavioural characteristic. Among the features measured are; face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions.

Biometrics systems are at the very forefront of access control innovation. As computer and image capture technology has increased so biometric systems are being becoming more prevalent. At present biometric systems are not mass market items, there use is limited to high security situations. With lowering cost and performance increases these systems are becoming accessible alternatives to conventional access control readers.
