Access Control - Technologies

Cost Effective Technologies

Keypad code entry:

One of the most common types of unit is the keypad system. This comprises a terminal with a series of numbered push buttons connected to the door lock release mechanism via a control unit inside the protected area.

Magnetic stripe swipe cards:

This technology was widely used and has the card reader installed adjacent to the entrance door. The card is “swiped” through the reader to gain access. Cards are the same size and appearance as credit cards and work in much the same way.

Proximity fobs or cards:

The advantages of this technology over magnetic stripe lies in the fact that the card does not come into physical contact with the reader it only needs to be held about 100mm from the reader.. It is more vandal resistant and reduces the wear and tear considerably.

Other Technologies

Smartcard Readers:

Smartcards and readers have the advantage of being able to store additional information which can be used for other services, such as library membership, cashless vending or storing biometric templates. They can be supplied in ‘read only’ or ‘read/write’ formats to suit needs. There are two variants of smartcard readers:

Proximity (contact less)

Insert (contact chip)

Biometric Readers:

This type of reader allows entry only if the authorised user’s unique human characteristics are recognised. This raises the security level significantly. Different types are available, which store the geometric patterns of the user’s retina, hand, face or fingerprint in an electronic memory.

Hands Free Readers:

Using active cards which transmit a signal, you can automatically unlock or open a door when the receiver detects the card. This makes it ideal in respect of the Disability Discrimination Act, as no action is required by the card bearer.

Your Mobile Phone:

Using an App which transmit a signal, you can automatically unlock or open a door when the receiver detects the phone.
