• This type of access control is most commonly used in blocks of flats or apartments, where access to the front door needs to be controlled remotely. Communication between the internal phone and the outside speaker is established, before authorisation to enter is granted.

Code-Based Access System

• A secure pin code entered onto a touch pad/screen is required, before Access to a controlled are is allowed.

Magnetic Stripe Card Technology

• Magnetic stripe cards are the size of credit cards and use the same technology as cash point ATM cards. The card information is stored to the magnetic stripe and is read by "swiping" the card through a card reader at access point.

Proximity Technology

• Proximity systems use cards or tags that are presented to readers to operate the access control. The card or tag does not need to make direct contact with the reader but must normally be placed within 5cm to 10cm of the reader. Proximity cards come in a variety of sizes but most modern systems use a card the same size and thickness as a credit card. Proximity tags can be clipped to key rings and can provide a more convenient and robust method of operating the access control reader.

Smart Cards

• Smart cards are the next generation of proximity card and have numerous security applications. The reason for this is they have a much larger memory capacity than proximity cards and whereas proximity cards provide "read only" information, smart cards are a "read/write" device. This enables them to receive and generate information for a variety of applications.

Biometrics

• The newest technology in access control, biometric systems use the body's unique characteristics such as the retina, fingerprints or palm prints to determine authorised access
